…after too long off it.
16 miles, riding in the hills near my house in Sunland on Sunday, took my pulse rate up to 163 beats per minute, almost 98% of my theoretical maximum (which, if you’re not too familiar with typical pulse meter readings, is more or less stunning).
My breathing has been stellar the last few days, so I’m guessing that the high pulse rate is due to:
(a) 13 months off the bike, and
(b) the recent ALYX blood donation, which takes a double-dose of oxygen-carrying red blood cells. I’ve read complaints from athletes that it makes a noticeable difference, compared to a normal donation.
I’m lucky to have these lovely hills so close that I can literally step out of the house, hop on the bike, and be among them just a few minutes later.
I didn’t have any problem actually climbing the darn hills; the only limiting factor was some lower-back pain, and then last night, some leg cramping, both of which definitely have to do with lack of practice.
Next up: a longer ride later this week!
