Yesterday, I set a new record for average speed. The course was an out and back on the Tulsa Riverpark East Trail, starting at the 41st St. trailhead, and turning around at the fork where the trail branches under or across the 96th St. Bridge. Winds were light, about 7-10 mph out of the South. The trail is almost dead flat, with no significant climbing.
The outbound leg was almost straight into the wind, and I had to push to average 18.4 mph going out. Coming back with the wind, I averaged about 21.1 mph for the return leg.
Sat down for a few minutes to catch my breath, and when I got back on the bike to ride home, I noticed the back tire had gone flat. I have no idea how long I rode on the flat tire.
I did the 12.4 miles in just 37:56, for an average speed of 19.6 mph. Maximum speed was 27.2 mph. Average heart rate was 158 (84% of max). Maximum heart rate was 171 (90% of max).
