Last Tuesday we did a group ride in the hills East of Gilroy that started at the Mendoza ranch entrance to Harvey Bear park.

Ever since my aortic valve replacement in 2017, I have been on the beta-blocker metoprolol. This is mostly to prevent possible heart arrhythmia but also helps control my blood pressure. It seems to be working fine and I have no noticeable side effects, other than my heart rate doesn't seem to go up quite as … Continue reading The Effect of Metoprolol on Exercise →

On Tuesday my group rode out to the end of Redwood Retreat road and back (to the Southwest of Morgan Hill). I did a long warm-up before meeting them, turning this into a 3 hour ride for me.
