Bristol South CC Megahilly definitely lives up to its name. With 1,100 metres of climbing in 28 miles, it makes a strong claim to be the hilliest TT in the land – especially in terms of vertical ascent per distance. If I got to design a time trial course myself, it would be difficult to design a course more suited to my strengths than this 28 mile test, taking in 5 long climbs around Wootton, Dursely, Frocester, Uley and finishing off with Stouts hill.
Mega Hilly
The Mega Hilly begins in the historic town of Wotton on the Edge. Straight from the startline, there is a testing climb of around 10%. It is nearly 150 meters of ascent right to the top. Though towards the end, the gradient eases off to be just a long dra.
With smooth tarmac, it is tempting to go off too quick. But, after the pacing mistakes of Buxton MTT last week, I was determined to hold back and not get overexcited. At the top of the climb, you turn left for a tricky descent into Dursely. The descent was still wet from overnight rain – I took it steady, especially with tubs pumped up a bit too much. At Dursely, you turn back towards the village of Uley and a long drag along the B4066. After you exit the village of Uley, the gradient increases, and I soon found myself in the bottom sprocket 39*25.
From the top of Cockadilly, you turn left down Frocester Hill. If you’re not racing, there is a fantastic view towards the Severn estuary – you can see for miles around. After a testing descent, there is a rare section of flat roads towards Easington where you do a U-Turn around a mini Roundabout. This was a chance to get low on the TT bike and pick up some seconds.
Road bike vs TT
There were quite a few riders using road bikes for this course. Road bikes must be tempting for quite a few reasons – better braking, lighter uphill, easier to manage on the corners. But, although they can be a bit unwieldily, I think the TT machine is always going to be 1-2mph faster (TT vs Road bike). Though I’m also pretty used to the TT bike as I’ve been training on it a lot. I rode a discwheel on the back; the only concession to gravity was using an ultralight weight ‘Lightweight’ front wheel, which rarely sees action outside the hill climb season.

Frocester hill
After a few miles of flat, your speed soon falls as you hit the lower slopes of Frocester hill. Frocester is a real beauty, nearly 200m of vertical ascent at an average gradient of 9%. I once cycled a round trip of 120 miles from Oxford just to have a go at Frocester hill, it’s definitely worth a visit to this part of the world. After surmounting Frocester, you turn left and there are a few false flats before another descent through Selsley into the outskirts of Stroud.
