hi, i was just wondrin why people training for flat road races train so much on climbing? i mean, like, if you see Lance's program, he spends so much time in those French mountains, and yet, in the Tour, there are very few mountain stages. yes the day to day stages do have rolling hills and all, but the majority of those stages tend to be flat / slightly inclined. Arent you supposed to spin on flats more than you climb if you are training for flats? or is climbing really that helpful??
