So I started flex time this week, enabling me to get my rides in to and from work. 6:25am get on train in Sac, 7:55 get off train in Folsom. Ride to El Dorado Hills 10 miles away with 2 "climbs" halfway through (they wouldn't be climbs on my TCR). Admittedly, the hills absolutely killed me - I haven't ridden up a hill on my F/G in almost a year. After 5 minutes of survival mode sitting on a curb, got on the bike and cruised to work.
The best part: 32 mile ride home, 20 on the American River bike trail, losing maybe 800 feet over the whole ride. This gives me a total of 42 miles and lots of "you ride here?!?" from the bewildered cubicle neighbors. Gonna try to do this 2-4 times a week except when it gets in the 100's in the summer.
