I hooked up with a local group down in Florida for a 52 mile group ride on Thanksgiving morning (on the TT bike). 10 flat tires (not mine and we stopped for most of them). 3 nature breaks and 1 crash. I pulled a lot. Slow except for a 6 mile section. I was waiting for one group as the back came through and hit the gas. I chased at 30 mph for a couple of minutes to catch on and then we stayed at that pace until a sprint line. Then back to slow. Nice and warm down there.
Went out again on Saturday morning for a 2 hour TT ride alone. Nice and flat with bike lanes everywhere.
