Mountain Bike (Roads) 1:27:30  20.0 mi (13.7 mph)
15 minute warm-up then 3x12 minute intervals with 2 minute recovery
Talked myself into riding outside today with the bargain that if I was cold at the 30 minute mark, I could ride back with the wind and then do my long cool down on the trainer (to warm back up?) but my layers were adequate and I was ok temp-wise for the first part of the ride. Actually, 2 minutes in it started hailing and raining, but that didn't last very long.
I really tried to focus on keeping my breath under control during these as I tend to breathe too fast on bike intervals (maybe because I'm used to breathing to a running cadence?) Anyway, focused on legs and keeping the breaths longer. Also, made sure that the last two minutes of the interval were the hardest. At the start of #3, I was thinking, oh, my legs are kind of achey. It went away, but the unfortunate song that got in my head didn't. (Achey Breaky Heart.)
Got cold halfway through the cool-down, but I guess it wasn't too bad.
