I tbink your find its 75hours these days.
Yes.
It started (will start?) at 8pm and we had until about 11pm several days later to finish in time, though everyone who did finish was pretty much finished by about 7pm.
1st edition in 1996, the toughest section of the ride between Minehead and Bovey Tracey was notably further than what was said on the routesheet and at least half the field were out if time at Bovey Tracey, where a lot of people packed.
Ridden all 3 plus rode the route in the time limit another time. Only ever ridden it on fixed. If I ride it again, I'll probably use gears to save a lot of walking up hills. If it fits in with next year, I'll ride or help at a control.
