At the end of the hill I was dizzy, feeling like I was going to throw up and that lasted a good 20 minutes further into the ride. Anybody could have sworn I was drunk because I was somewhat swerving down the road and pedaling like a ******. I guess I toped my max which usually is in the low 190's. I'm afraid this could damage my heart. I did, however, break my PR for various segments...
