Pushing to hard?
Hi new rider here. I'm male, 47yo, 5'10", 240 lbs and have been riding my bike for the last 4 months after not really riding for years.
I'm averaging about 60-75 mi per week. I use a HRM when I ride and have question. Looking at the zones over my last 20 mi ride I see that I was in Zone 4 - Zone 5 for about 90% of the ride. There is no dizziness or anything while riding. I experience burning in my legs from trying to keep my cadence up.
I guess I'm looking for info on whether I'm pushing myself to hard? Thanks.
