Shutting It Down

Rode for an hour to warm up on the rollers and then moved to the trainer to do Tempo workouts.....couldn't get my heart rate above 155, I tried for 25-30 minutes, no luck. I'm smart enough to know that it means to shut it down, so that was it for tonight. Maybe time to give the body a rest, I'll see how it responds tomorrow morning but maybe a couple days of recovery rides are in order. That's all, until next time....
