Why are breakaways nearly always caught – and when do they succeed?

September 16, 2019 by tejvan

I was chatting to some ‘non-cyclists’ interested in trying to understand why breakaways nearly always get caught a few km from the finish. I thought it would be a quick and simple thing to explain, but I ended up writing a lot.

In cycling, the biggest drag on effort is aerodynamics (up to 90% of drag when travelling at 50km/h). Therefore, you save considerable energy riding in the middle of the peloton. One study suggested that riding in the middle of the peloton can mean you only need 5% of the energy you would if you rode alone. You can be doing 50 km/h, but the effort is similar to 12 km/h. If you ride in the peloton all day, you can get to the last 10 km relatively fresh and ready to make a big effort.

Flowing data

If you ride in a small breakaway, you are making much more effort throughout the day, you will get some drafting benefit, but you will have to ride with your nose in the front for considerably more. When you get to the last 10km – the breakaway riders will be closer to exhaustion than the riders in the peloton. Then in the last 10km, there are fresh riders ready to chase down the breakaway and set up a sprint.

There will usually be many teams with a motivation to chase down the breakaway. The best sprinters will have a team willing to ride and bring back the breakaway. If a team doesn’t have someone in the breakaway, they might as well contribute to bringing back the breakaway – otherwise, they will have no chance of winning.

Secondly, if it is a one day race like the World Championships, the best riders will tend not go in the breakaway. Therefore, it becomes self-fulfilling, weaker riders enter the breakaway – either for tactical reasons or perhaps just to get some tv exposure.

A breakaway would have more chance of winning if there were more people in the breakaway and stronger riders were in it. But, at the start of the race, teams will be looking to control who gets in the breakaway. If a strong favourite tried to sneak into the breakaway, the peloton may chase down the breakaway and bring the favourite back – rather than let the break get established.

A more interesting question is what enables a breakaway to succeed?

What enables a breakaway to succeed?

Miscalculation. Teams may use a rough rule of thumb. For example, a fast-moving peloton may feel that it can bring back 1.30 for every 10km. If there are 20km to go, and the breakaway has a gap of 3.00 – it is touch and go, so they may start making more of an effort to bring it back. However, it may be that the peloton miscalculate the strength of the breakaway and leave it too late.

Tour de France 2019

July 29, 2019 by tejvan

The 2019 Tour de France was a memorable edition of the race. Team Ineos were relatively weak but still walked away with first and second place. After Alaphillipe and Thibaut Pinot lit up the race to the excitement of the home nation, the only French podium was Romain Bardet – not something you could have predicted from the stage on the Tourmalet. There were many highlights of the race, but the sight of Alaphillipe racing away on short climbs to nab the yellow jersey and then hold on for such a long time, were probably the best. It’s not often you get excited about time trials, but Alaphillipe racing up the final climb of the TT stage with thousands of French roaring him on was a goose-pimple moment – he was going so fast, he could have been doing a 1-minute British hill climb.

Supporting the French

July 22, 2019 by Tejvan Pettinger

It’s been a really great Tour de France. I’ve even found myself supporting the French! But, now it reaches the third week, I hope Geraint Thomas comes strong and nips past both the French riders on the last day in the Alps. I don’t think it is so much supporting the French as hoping for an interesting race, where many riders are in contention and with each stage, you can never be sure how it unfolds. Also, it makes a huge difference when one team doesn’t have a dominant mountain train to discourage any and every attack.

It has always been a shame that the Tour de France is usually the ‘flattest’ of all Grand Tours. The Giro and Vuelta rarely fail to give real interest in the GC, but – despite the odd edition, the Tour de France GC usually ends up being fairly predictable. But, this year it is all up in the air and there seems to be a lot more positive energy around the tour. Crashes are down; there isn’t even any doping saga hanging over the tour.

I think the organisers are finally cottoning on to the idea that seven flat sprint stages don’t make for great tv. I expect for the next few years; there will be a lot of Alaphillipe style stages with short viciously steeps climbs just before the finish. If the Tour is short of ideas, I would recommend going back to Yorkshire for a good week!

Watching the tour go up the Tourmalet was a great experience. It is one of the few Alpine* style climbs I’ve ridden – what an amazing amphitheatre for sport. In terms of drama, it couldn’t match Sunday and other previous stages, but I was just enthralled by the spectacle and scenery. How I would like to be climbing up the Tourmalet on top form.

Nobody can predict with any certainty how the next week will unfold, but there is an old adage in the tour, that the best guide is a rider’s record in previous Grand Tours. Form and panache are one thing, but does the rider have the staying power for three weeks? With this in mind, I would put my money on Geraint Thomas – but not very much. He’s still struggling to gain the leadership of Team Ineos. But, a big thing in his favour is the proven ability to stay strong for a whole three-week tour. It is possible that the Alpine climbs (which are not quite as steep as the Pyrenees, will suit Thomas more than the Pyrenees.

Bernal, Alaphillipe, Buchman, Landa and to a lesser extent Kruijswijk all look very good, but as of yet, they don’t have a strong track record of winning a Grand Tour. If Alaphillipe cracks in the Alps, it will be easy to say we all expected it. But, if he doesn’t crack we will also say – well he had such good form why would he crack? It always looks obvious after the event. Anyway, the school holidays are here. A rest day today, Tuesday flat stage, but who knows a strong wind could make it very interesting.

(* I know the Tourmalet is in the Pyrenees, but I always find Pyreanean an intimidating word to spell.)

World championships in Bergen and a new book

September 27, 2017September 25, 2017 by tejvan

The World Championships in Bergen, Norway were a great spectacle this year. It’s still hard to believe that last year, the UCI decided to hold their flagship event in a desert. But, it was good to see a transformation this year with a beautiful backdrop and enthusiastic, well-behaved crowds. It really adds to the spectacle, and let’s be honest often, for a long time not very much might happen in a cycle race.

I particularly like the men’s time trial course. A flat 40km and then a proper climb at the end. I’ve always fancied time trial courses like this. But, in the UK we seem to do them the other way – descent at the start and then flat to the finish. But, it was fantastic to see so many spectators on the last climb. And mostly they were very well behaved. The odd one who misbehaved got properly treated by the Norwegian Police.

Chris Boardman – Autobiography – Review

July 28, 2017 by tejvan

A few weeks ago, I received a review copy of Chris Boardman’s autobiography. This week I got around to reading and enjoyed the book. In terms of cyclist autobiographies, this ranks quite highly. It is interesting story, with many different aspects of cycling from domestic time trials to wearing the yellow jersey in The Tour de France. As well as his cycling achievements (and failures) you get a glimpse into the personality of Chris Boardman, and perhaps what he has learnt in life. There is a degree of humour and honesty which make the book an enjoyable read. If I had to choose a cyclist from that period of cycling who I genuinely admire, Chris Boardman would be near the top of a very short list. There is also the added interest of the fact that I can relate strongly to his early career (riding domestic time trials and hill climbs) I have followed Boardman’s career from the epic time trial battles with Graeme Obree reported in “Cycling Weekly” to his emergence as a sane and powerful advocate for better cycling on British roads.

If any cyclist epitomises the spirit of British cycling it is Chris Boardman.

Domestic time triallist, multiple national champion – from national hill climb to national 25 mile TT competition record holder.
Olympic track cyclist. Gold medal in 1992 Barcelona Olympics (Britain’s first gold on track for 72 years).
Three times world hour record holder.
Multiple world champion on road and track.
First British wearer of yellow jersey since Tom Simpson in 1968.

Tour de France 2017 review

July 23, 2017 by tejvan

This week I have been ill (again) so took advantage of the ability to watch some stages of the Tour de France on TV, from start to finish. I’m not sure whether it is actually a good thing to have the whole stage on TV, there are only so many French chateaux you want to see per day. Even the most ardent cycling fan can get bored of a few hours with the peloton plodding away.

At least this week, there were none of the completely flat 200km stages. Some individual stages were quite interesting and, even if the GC battle didn’t completely fire on all cylinders, at least the small time gaps were sufficient to give hope.

Overall, I thought it was a good race. Compared to watching the tour 15 years ago, I like the cyclists involved. I haven’t followed the recent furore of TUEs too closely, but it seems the peloton is very different to the bad old days of ‘he must not be named.’

I like seeing French riders do well, and it was a good tour for the French, who have the most exciting crop of new cyclists. This year Froome showed fewer signs of invulnerability, and a future French winner in a few years looks a real possibility. Whether it is Bardet, Barguil, Lilian Calmejane or Pierre Latour – they have a lot to choose from.

L’Equippe evaluated that if you only included the mountain stages, Froome would have finished 3rd. With the winner being Uran or Bardet (can’t remember which). In the last time trial, Bardet did look completely out of place fighting his time trial bike up the steep hill; from my armchair, he looked more like a club rider doing the Buxton Mountain Time Trial – than a Grand Tour winner. Chris Froome went up the climb like he was completely in control. After the stage, Steve Cummings admitted he thought his team had got their gearing wrong and were over-geared making the climb too difficult. It seems such an elementary mistake of getting the wrong gearing is something that every team is capable of – every team – except Sky of course. Whatever you think of them, they always seem to be the best prepared. Though it does help when you have the talent to go with logistics. You could have had a pretty good Tour de France GC battle, just between members of Sky – Geraint Thomas, Mikel Landa, Michael Kwiatkowski all seem to have the capacity to win a Grand Tour.

In the end, Bardet’s dire time trial (dire in relative terms, of course) was just enough to keep the podium place by one second. If Sky’s Landa had pushed the Frenchman off the podium at the last minute, the atmosphere might have soured even more.

Not that it seemed to bother Froome. In responding to the challenges of a Brit riding in France, Froome frequently shows a degree of emotional intelligence and maturity which is rare in top sportsman. Another sportsman may have been peeved, but to his credit, Froome laughed it off as inconsequential. It is an attitude which gains the admiration of many – maybe even the French on the quiet. To put in perspective, Merckx and Anquetil (a Frenchman) both were booed – their crime to be the dominant rider of their generation.

I think Bardet should come over to the UK for a few months and learn how to ride time trials. A few times up and down the V718, getting beaten by 45-year old amateurs and he might learn to keep his head in the right place.

The other interesting thing is whether the organisers of the Tour de France would dare to remove all flat time trials and make it a tour for the French climbers?

Tour de France 2018

Looking forward to 2018, there is a bewildering range of possible challengers to Froome.

Tom Dumoulin (Giro winner and top TT)
Richie Porte (shame he crashed this year)
Nairo Quintana (who presumably will not do another four Grand Tours in succession.
Romain Bardet (if he can get better at TT’s)
Rigoberto Uran (who crept up anonymously into second place, refinding the form of a few years ago
Warren Barguil. Whose ability to climb away from GC riders on the last stage was quite impressive.
Fabio Aru. (yellow jersey wearer who might need to practise riding in Chris Froome’s wheels a little)
Mikel Landa (as long he doesn’t stay at Sky)
Dan Martin (maybe doesn’t quite have the legs, but he deserves to be up there for his attacking attitude.

Then there is the next generation of riders, who may or may not be able to make the next leap forward. From this list, you could pick from many of the Yates brothers, Pierre La Tour, or Louis Meintjes

There are even possibility of riders who won’t be able to challenge because they are super-domestiques, a la Geraint Thomas and Kwiatkowski.

Tour de Yorkshire 2017

May 1, 2017 by tejvan

I enjoyed watching the Tour de Yorkshire – recognising roads often cycled on, huge crowds, familiar climbs and quite a few local riders I have raced against at different times. People say the crowds are as big as Liege-Bastogne-Liege but the last time I watched Liege-Bastogne-Liege, I didn’t see any crowds on the scale of Yorkshire.

I spent more time watching Tour de Yorkshire than the Tour de France. On Saturday I enjoyed seeing Lizzie Deignan and Anne van der Breggen fly up the Cote du Lofthouse, that was a good race. The third stage on Sunday was great because it went past my old school Bradford Grammar, up Hollins Hill and past Menston all the way to Burnsall. Yesterday, there was tremendous interest in the page on Shibden Wall – the 21% cobbled climb.

Watching tv, I thought the Peleton weren’t going at full flight on Shibden Wall – perhaps not but when I saw the times on Strava I knew that looks can be deceptive – it was still pretty quick. I have ridden it once and now want to go back and have another go.

In the end, after 10,000 ft of climbing, it was a good finale to the race with Serge Pauwels hanging onto a slender advantage and taking the first win of his pro career.

I took some shots of my tv, but it doesn’t do justice to some of the crowds in the road.

The Tour de France vs the Vuelta Espagne

September 4, 2016 by tejvan

The Vuelta is the youngest Grand Tour (formed 1935) and has often been in the shadows of its more illustrious rivals – The Tour de France and the Giro d’Italia. But, in recent years it has often provided the highest quality racing and also provided a showcase for emerging riders to make a name for themselves.

The Vuelta is squeezed into a difficult slot in the calendar – September, just before the World Championships – but it often provides the most drama for the general classification battle, something that often eludes the Tour de France. The recent editions of the Vuelta have all provided great racing, intrigue and a see-saw battle between the top contenders. The organisers have thrown the rule book for grand tours out of the window and created stages which seem to create more attacking racing. Shorter stages, innumerable mountain tops. The sprinters union may complain and the likes of Cavendish, Greipel have voted with their feet – preferring the Tour of Britain. But, whilst it is good to see the top sprinters in full flight, the excitement lasts perhaps for the final 1km – it’s all over before you can work out where everyone is. What we really want to see is epic battles over mountains.

Peaking for the four year Olympic cycle

August 13, 2016 by tejvan

I’ve had a few injury niggles this week so haven’t been able to do as much cycling in Yorkshire Dales as I hoped. Cycling has mainly involved pottering along to Bolton Abbey, I’m getting a bit restless to do some hill climb intervals – I haven’t really done much this year. But, although it’s frustrating to take it easy and dns for a race today, there is considerable compensation in watching the Olympics.

Great Britain has made a great start to the velodrome; in fact to an outsider it can appear winning a gold medal is almost taken for granted, but GB men’s sprint team was 15/1 at the start of the games. The last time they won a major championship was in 2012.

Chris Hoy makes a good person to have in velodrome. He is is articulate and passionate, with a certain gravitas – not always present with BBC presenters. Though, last night, he kept looking over his shoulder trying to watch the racing going on behind – rather that answering endless questions on Bradley Wiggins’ frame of mind. I must admit I would have rather watched the racing too.

Still in the end, the 4km pursuit final was a real epic contest. Defying the pundits predictions, Australia ran GB very closely. When the third man of GB got slightly detached on the last lap, it was really touch and go. It was an epic moment of the Olympics, for both Wiggins’ 5th gold medal, but also the closeness of the contest.

Confidence

It was interesting to hear the real confidence many in the GB squad have in themselves. After losing the worlds in March (by very small margin to Australia), Bradley Wiggins seemed utterly confident in saying “But, we will definitely win the Olympics”. If it had been someone else, it may have come across as bravado, but it was said with the real conviction, that they knew more was to come.

In another era, Ed Clancy’s 3rd consecutive gold medal would be headline news. But in the Olympic gold rush, post national lottery funding, he can, like Steven Burke, fly under the radar. But, I get the impression the likes of Ed Clancy, Jason Kenny and others are quite happy with their relative low profile.

Mens Olympic road race review

August 7, 2016August 7, 2016 by tejvan

The mens road race was a spectacular and dramatic event. Over six hours, the intensity gradually increasing to a dramatic final conclusion hour of racing.

Box Hill — 2012 Olympics – Box hill – Sum of Marc

During the Tour de France I tried to limit my viewing time to 30-50 mins a day. I don’t have time to watch a whole stage. But, I made an exception for the Olympic road race, and watched the last 3-4 hours live. It felt like a three hours well spent. The scenery was beautiful, the setting epic and the racing high quality. It was helped by a good performance by the GB team, with a medal a possibility all the way until Thomas crashed out on the final descent. Everyone had a good race – Stannard and Cummings chasing the early powerful breakaway and then Thomas slipping into the first chase group as the race hotted up. Yates latching on to lead group, but not quite having legs. Froome didn’t have the climbing legs of the Tour, but considering his one day history, had a reasonably good race.
