So far this year I have made a 100 k + ride 4 times - as have Mike and Steve. St. Francois Xavier and Highway 26 on Canada Day, Niverville on July 31, the Muddy Waters Ride through East Selkirk and Bird's Hill Park on August 14, and East Selkirk last Sunday August 28. In spite of rain, I have kept up with the distances I rode last year.
There have been some complications. I had an odd feeling in my right hip and a little pain in my right knee most of the year. I tinkered with my seat height and seat alignment on both bikes, and with cleat position before finally noticing that the seat on my heavier urban bike had actually worn out and canted down on the right. I realized that I had not been having those problems when I rode my road bike. I replaced the seat on the urban bike last week. I suspect I had mild bursitis in my right hip, from the uneven position of my hips on the saddle. Having fixed that - but not recoverd or healed yet - I ran into a new problem. I changed the stem on my road bike from a 70 mm extension to 90 mm. The next time I rode that bike - last Sunday, I had intermittent tingling in my right leg, radiating into my right arm. That seems to be a stretching issue, getting loose before getting on the bike, watching my posture, getting accustomed to the changes in my body position. I did a hard sprint up the Arlington Bridge, twisting my neck to look for overtaking traffic, early in the ride. That may have aggravated my sore hip enough to set off the tingling.
Live and learn.
