Today's ride was a 120 km ride to Burlington and back with largely the same route as on
May 23. I decided to travel ultralight today, and I only brought 750 mL of water and two granola bars, of which I only ate one. Riding without my backpack felt fine, though it was not a dramatic improvement. I started late enough that I encountered some traffic and more red lights than I would have two or three hours earlier.
I ate a clif bar 1:15 into the ride, and I took a slightly different route - riding Speers Rd on the outbound in lieu of Lakeshore. Speers seemed a bit slower than Lakeshore, with more red lights and passing near a mall.
I rode fairly hard, and it was encouraging that I averaged comfortably over 33 kph outbound on any stretches without stops (e.g. 2 km autosplits). I stopped at Spencer Smith for a few minutes at 63 km, drank some water, and took in the vista of the lake. I had planned to eat a granola bar early on the return leg, but I decided to avoid it to see how I would feel and to train digging deep when hungry. Perhaps because of this, I had a few slower stop-less splits, with a couple 2 km autosplits below 30 kph. I was definitely fading after 100 km; any time I really cranked up the power, e.g. to go up a hill, I found my available power reserves very shallow. I suspect I would have bonked hard after another hour or two.
Unfortunately, my rear tire went flat at 111 km. I had two tubes with me - the first replacement had a very short stem, and my minipump couldn't quite make a secure seal. The second tube stem was about a half inch longer, and it was a relatively quick exchange. I'm not fast at tube replacement, and it took about 30 minutes total with all the stem challenges - not aided by the fact that I only had one tire lever. A skill to work on for sure.
Garmin died, as it evidently wasn't fully charged when I started. I started riding home on St Clair, but the street has so many painful stops, and street parking kills one of the two lanes - which both slows travel and increases the interactions between cars and bikes. At Via Italia, I dropped down to Davenport and got the added bonus of a fun hill up Poplar Plains.
