Didn't get out quiiite as early as preferred (dogs!) given the (correctly) predicted heat and humidity, but it coulda been a LOT worse. Especially with the MULTIPLE stops to deal with the rear tire and various user errors. Been running tubeless on this bike and liking it ... until today when it just would not keep air in it. Is there a hole? Nope. It must be leaking from the valve then? mmmm, nope. Finally, after several pump-up-the-jam, uh, tire sessions, decided at 14.9 to do what should have happened several stops earlier and put in a tube. Got the tire off and ... whaaaa? It's got a clear liquid? Where's my Stan's? (Narrator: Stuck to the tire, dummy, which you had apparently not ridden in awhile?). SIGH. Put in the tube, pump it up and voila, no more Flatty McF! Thought about cutting the ride short and heading for home but decided, nah, now that it's holding air, finish the planned route. That was the right call. It was ... hot ... by then, but not overwhelmingly so. Legs are feeling much better and none of the climbs gave any problems.
