Many thanks for the information/suggestions particularly on the monopedal techniques and fan wheel effects of gaffer tape.
As you say, not much info hereabouts on training with rollers. This is what I've been up to in the barn:
After several 30mins (by the tin clock) 'spinning' sessions to familiarise myself with rollers technique I splashed out on a cheapo bike computer. I started doing a daily routine of 10kms keeping above 20kph with the penultimate kilometre at 25kph. This felt comfortable after few days so I upped it to 15kms with the same speeds. When this gets comfy
I'll up this again to 20kms and introduce further intervals at a higher speed (i.e. at 3km, 8km, 13km and 18km). Then it's up to 25kph average with 30kph intervals.
The weather here in Wester Ross is still character building so little/no road work for me yet but the rollers are providing 2 wheeled entertainment in the long dark evenings. Failed to get an entry for LEL so we're aiming at another long and winding road for 2013 - on 3 wheels naturally...
