i'm back on the bike in a serious manner after about 12 years off. just finished my first century of the year on sunday. no question for me of taking a couple of days off. in fact, the weather forecast has wind gusts to 45 tomorrow, so i may take 3. if i do go out, it will be in the woods on the mtn bike. i have been averaging 4 days a week. at 65 i just can't do the endless every day riding i used to handle just fine. but with rest i've been able to average about 125 miles a week pretty comfortably. i resisted the urge to join a couple of groups on the ride sunday that were too fast for me, most awkwardly from 4 guys who were my age or older. but going my pace i finished right at 7 hours. rest is key!
