After the long run yesterday, my schedule called for a 90-minute bike ride. I had planned to do a smooth ride around DC Ranch but ran out of daylight hours. I ended up doing 90 minutes on my trainer at home. It is no fun doing longer rides on a trainer. It is monotonous and boring with the same cadence, same speed and same effort for almost the whole ride. It is also a perfect recipe for butt-blisters (I know, TMI).
