signed up for trainerroad and downloaded a sufferfest video to make the turbo sessions more bearable.
what resistance level should I set the turbo trainer on? or does this not matter as long as I've got a decent range of gears to allow me to keep the displayed power at the correct level?
eg if mine is set in 3 now, if I drop it to 2 (and change it on trainerroad) will it mean I just have to use higher gears to get the same virtual power output?
Consistency is key...set it up, do the FTP test (enjoy that!) and try to replicate the conditions thereafter...same resistance, tyre pressure etc. as best you can.
I've not it backed off the resistance but would guess your cadence would need to increase fairly significantly assuming the same FTP/virtual power.
