BBL iBike data and videos

Fun day today at the BBL. I mainly wanted to put a post up with my iBike data for those of you curious about the iBike. I’ve highlighted the attack zone data below first – along with a video for the Sterrett attack zone and the Vandiver KOM. I forgot to turn the video back on for the Mimosa attack zone. The format for the post below goes like this: 1) data 2) graph 3) video. Then I’ve got the data and graph for the entire ride at the end.

BBL power records

Today’s BBL was quite a ride … Strava marked it in the “Extreme” category, and I set two new power records. Ironically, they both came in the first attack zone where I went too early and got caught in the last 50m before the line. The power map is quite colorful in the attack zones where you can see some of the tactics playing out. Here are the graphs!
