Well, after posting earlier today I ignored my intention to take it a bit easier. Rode a quick errand to the LBS to pick up a tool. It's only a mile but all uphill, which is always a tough warm up ride.
By the time I finished at the LBS the weather was looking ominous, so rather than the 20-30 mile ride I'd intended I decided to tackle a couple of nearby Strava segments to see if I could improve my time.
I beat my own KOM by 2 mph. Felt good, after I caught my breath again.
That lure of speed and rush of blood to the brain after a hard sprint... it's almost addictive.
But tomorrow... tomorrow I'm gonna try to make it a casual ride.
Try.
