So I took my first real ride today...prior to this I had done a couple of 10 mile runs but on very flat routes. This one was through Worcester, MA and anyone that knows it, knows that it's hilly though I wouldn't say my route was particularly so. I rode to my gym, worked out and rode back. A 10.25 mi loop separated by 60 minutes of circuit training and 45 minutes of cardio (that might have been a mistake). My average was just over 12mph but I was slowed by a front derailer issue. The cable had snapped while on vacation and I took it to my LBS to have it replaced, it shifted fine the first couple of times and then it would take it's time if it went to the outer chainring at all. The derailer didn't move and I'm wondering if it's as simple as a stretched cable. Retensioning looks like a breeze, any thoughts? We just got a bike trailer and were going to take spartan113 out for a ride Sunday.
