Cycling 12:00  2.0 mi (6:00 / mi) +50m 5:34 / mi
Took a vacation day from work to rest from the Traverse, rake some leaves, and enjoy nice weather. There was a blood drive today up Salisbury St from home so I biked there.
No strenuous activity post-donation was no problem, since it was mostly uphill going, pre-donation, and mostly downhill post-donation. I didn't bother to pump up my tires, but the bike handled very squishily. I feared the rear wheel was not locked securely into the QR, but made it home safely.
Triceps extremely sore from catching myself by tree limbs on downhills yesterday. I think other AP'ers have reported similar physical effects.
