76 degrees when I started at 1100, and 83 degrees when I finished at
0215. I've been going to experiment with tire pressures and I did it
today. I've read about people reducing their pressure and not having
any trouble. I started with all three at 70 PSI, but I felt like I was
slower and pedaling harder. I stopped and used my new battery pump to
pump them up to my usual 80 PSI.. I really felt the difference. Next
ride I'll try 85 PSI.

Did you time it? In my experience and others higher pressures feel faster
as thatrCOs just how our brains work, the vibration feels fast.

This said tyres like Marathon, with fairly stiff sidewalls arenrCOt likely to perform well as you lower pressures, IrCOd also guess the cycleway is fairly smooth?

Since I commute and generally have been on Strava a long time I can compare tyres which was useful as you do feel the squish which feels slower, even
if the time shows no difference.

It's mostly older asphalt that's worn down a bit.

I can see on the garmin charting that my speed pick up a bit,
although, admitidly, it could have been simply because of the resting
time it took to pump them up.
