I've just done a 10 mile TT on that course this lunchtime. Like you, I had not done the course before. It's a short loop, half of it or so uphill and the rest flat/downhill. A course that should suit you Martin I'd have thought.I didn't get to race (or ride at all) yesterday - so tonight I'm doing the following race. It is on Queen's Highway which I don't think I've raced before.
It is 13 laps, 25.9 miles and 565m of climbing, so will be quite challenging. This will be my first Zwift race with the British Masters mob. They are joining this race but don'r run it. It looks as though Eric Schlange (aka Zwiftinsider) is racing as well - in the B Cat so could be interesting.
Anyone coming to play?
