So, I had two 'great' rides this weekend (felt good, minimal suffering except for a few short steep hills, mostly dodged the rain), and I got the garmin HR monitor working again (after several weeks of confusion, duh...) but I'm not sure I believe the results:
Both rides report an ave. HR of 149, which according to Ride-With-GPS is right on the border line between aerobic and anaerobic - but I'm not at all feeling like I'm rolling at that point (mostly, except for the hills my breathing is relaxed, I would describe the pace as 'moderate' - certainly maintainable for 2-3 hours.
My training / riding goals are first continued weight loss (-21 and progressing), then prep for century / fondo type rides, then (a bit further out) I'd like to try some racing...
So, my questions are these:
1) Am I committing the training faux-pas of just riding too hard too regularly?
2) Are my heart rate zone estimates bogus? (per rwGPS, they are z1: 116-127, z2 127-138, z3 138-149, z4 149-160, z5 160-171) - I know this is very individual dependent, so maybe the question is this: is a max heart rate of 171 in the expected range for a somewhat overweight 54 year old? It seems low to me.
3) Or could it be something completely different?
thanks in advance...
Now that I've typed this up, I'll go do a search to see if its already been covered...
