09-12-2024 Ride

I went for an early-morning walk/jog, sprinkling in two 30-octave jogs per mile. Finished the 3+ miles in around 50 minutes. Then I had a fairly quiet morning, not doing much around the house. I rode over to HP to meet him around 11:30 and help with the Tech Man Tri training ride. Headed through the neighborhood and over to Via del Campo, then around the back side of the campus to meet the riders near the back patio. There was only one other rider who joined us, Paula Dragu, who Blair had met on the Padres Pedal for a Cause ride. She is a solid rider, not super fast but experienced with longer distances. Before we left, I had a short conversation with Linda Vaisman-Rashkovan, who is looking thinner and her hair is growing back. On the ride, we headed out Bernardo Center Dr down the hill and up Carmel Valley Rd, past Black Mountain and then down to Camino del Sur. I was sweeping on this ride, so my pace was modest the entire time. Right on Camino del Sur, then we followed it all the way back to Bernardo Center Dr, where we turned and rode back to the starting point. It was a simple loop, and the weather cooperated well, not too hot and with a little offshore breeze pushing us on the return segment. Then I rode home the normal way from there.

Avg speed = 13.7 mph. Total mileage = 18.3 mi

Avg power = 105 W. Weighted avg power = 144 W

Total elevation gain = 1280'

Avg heartrate = 111 bpm (Coospo)

It was a light day for the rest of the afternoon and evening. I spent a fair amount of time working on the GPX file analysis code to get a better, working version of the routine for marking Strava segments along a given ride. This is turning out to be more complex than I originally envisioned, but at the end of the day I had some breakthroughs to get a first working version. Still likely to be bugs in the code, but it was gratifying to see the code spit out the starting and ending Strava segment positions. A major issue currently is that the code is slow. As an example, processing a large GPX file, 70 miles and sorting through about 150 Strava segments, took about 5 minutes, not super bad for a batch operation but unworkable for real-time analysis. It's hard to see how I can speed this performance up by an order of magnitude, but at least I got the logic worked out.
