Spin Class

So first spin class this year (2010/2011) last night.  Started out the class about 20 minutes early and decided after listening to the encouraging statement from the guy behind me 'we do a medium pace until on of you rassy guys fly by then we try to catch up'  So I killed it for the next hour and my legs still hurt.  I'm not sure how the power meters work on spin bikes but there is no way I can put out 478 watts.  After the class the buy next to me who is not totally drenched says ' you worked really hard there'.  It feels great to get a good cardio workout in.  So maybe I'll make a couple more spin classes this winter.
