i agree that training helps! i only jumped on a bicycle in november last year.. did a 30 km on the first day with probably 6 stops.. and i wanted to quit.. rode the argus on sunday and completed in 4:04 i didnt over push myself, and i know i could have done it maybe 10-15 mins quicker.. but i enjoyed my first argus with no cramps.. (all due to the training)
