Arrived in Traverse City this afternoon and rode the 40 mile round trip up and down the Old Mission Peninsula. Had a flat at 12 minutes in but then hit the tempo for 36 minutes at 300, took off 4 minutes and then did 12 minutes at 301. While at an overlook some guy came by so I finished my pictures and took off after him. He was definitely hammering. Took me a couple miles to catch him. I held a pretty steady 340 for a mile or two just for fun and dropped him. You can see the end of the graph has some higher power spikes.
