I usually walk up and then run down but my HRM is usually beeping before I am done going down the hill.
I would love to be able to run different paces, but my only option is slower, which I can't live with if it is going to be 20 minute miles. I don't mind 15 minute miles, but 20.... arghhh!
Any ideas of what I could try? Someone earlier mentioned he bumped his HR up to 150, from 140, and saw some improvement. I know at that point it isn't MAF ...
Thanks again for your time.

If your MAF is 140, you might be interested in the following data. I got access to the measured Aerobic Threshold (AeT) and Anaerobic Threshold (AT) from VO2 tests taken by 70-80 local runners (some cyclists, some do triathlons.) Here are Aerobic Thresholds for people aged 38-42 who took these tests:
106, 108, 163, 107, 162, 116, 153, 159, 110, 160, 129, 128, 133, 158, 133.
Notice that there's quite a spread here. Are you a 40 year old with an AeT of 116, or is yours 153? Maybe you're like a 41 year old with an Aerobic Threshold of 160? The only way to tell for sure is to have a VO2 test.
Around here one can get a
good VO2 test (showing HR, RQ, and pace through your whole range... and more...) for under $200. From this you also get recommendations about training range(s) etc. The Respiratory Quotient (RQ) shows the % of energy from fat metabolism and carb (glycogen) metabolism.
As for "180-age" MAF? It's a start. Note though that in the data of 15 age 38-42 folks above, 9 of those 15 had an Aerobic Threshold 20 or more bpm different (lower or higher) than 180-age.
Your HR recovery rate might be a clue. How long does it take your HR to return to halfway between your MAF and your resting HR after you stop running and just walk
very slowly (not standing still...)?
Good luck in your training.
