now that it's getting a bit warmer out now, i'll be doing A LOT of kayaking on the weekends, so my weekend riding will be less now (though not gone entirely). but as a general rule, i don't find my 150 miles/week of bike commuting wears me out too much for weekend rides. but sometimes, after a longer 50+ mile ride on sunday, my legs feel more tender on monday morning than when i don't do a longer sunday ride.
