I've been off the bike for a week, and desperately need to get in at least an hour and a half of hard intervals this afternoon (no training ride this evening because of Passover seder). Before I can get out on the bike, however, I need to work ahead on class preps for tomorrow and next Monday. So, don't look for much more blogging from me today.
UPDATE: I got out for only 50 minutes, and my woeful set of intervals confirmed what I had been suspecting: I've lost a substantial amount of fitness over the last several weeks of only intermittent riding. Time to HTFU, ride more, and ride harder.
