Feeling a bit better, so exercise bike times. Really the only option up here for the winter. Well, with studded shoes/mountain boots I could probably make it up to the Pico Veleta, but I'm not sure they'd let me, bah.
Anyways, just 15 min warm up and down with 10 x 1 min on, 1 min off. Turned the resistance all the way up for the 'on', it's a pretty wimpy bike... ah well!
