Hi Fands, that was the 200km DC trial last year. Best exercise i have done in a long time, no excuse for bad weather. Sat 200 km on your own (to make sure you can do 200km on a bike) 2 weeks rest then 100 km TT Sat, light cycling for 2h45 in the week, next Sat 200km DC, 2 weeks rest then 100 km TT Sat, light cycling for 2h45 in the week, next Sat 200km DC, worked it out, it was over 1000km of cycling on the IDT. about 7 hours for each 200km = 21 H + 3H (100km) + 3H (100km) + 2h45 + 2h45 = 29 h 30 on the indoor trainer. They paid us a R1000 = R1 per K.
