The pollen today was terrible but the wind was light so I hit the airport for some in the end not very sprinty Sprint-Intervals. Meh; it was my first time at the airport in months.
By chance tho I fell in with a dude even older that I am — 79 year-young 1-Speeder John. He sometimes flips his wheel to ride fixed but today was a free day for him.

I managed to get a good but much too long video of us on our laps. Any committed cyclist that old eschewing gears is an inspiration.
