paul the builder Sep 2017 3:33pm, 5 Sep 2017 6,205 posts	Quote Pin paul the builder I used to try to understand FR's performances, and his posts about them. But never could. Certainly ""Doubt I can run a marathon at 75% without the wheels coming off and the last 10k being absolute torture"" makes no sense really for someone with all those years of running under their belt.

Fenland (Fenners) Runner Sep 2017 9:09pm, 5 Sep 2017 13,422 posts	Quote Pin Fenland (Fenners) Runner I'm wondering about the margin of error? Is it like MaxHR being 220-age? Perhaps I'm just an outlier.
chunkywizard Sep 2017 9:39pm, 5 Sep 2017 4,741 posts	Quote Pin chunkywizard I reckon I get 5% drift over a half so perhaps on a full you could drift 9%?
Daz Love Sep 2017 8:58am, 6 Sep 2017 709 posts	Quote Pin Daz Love FR - 220 - age can be way out. I am 43 so 220- 43 = 177, I got up to 195 in my 10k on Sunday with average at 189. Still not 100% sure on my max but see 198 in a race not so long ago. If you are basing you % on that formula then that could be the reason.
Huntsman Sep 2017 10:32am, 6 Sep 2017 5,529 posts	Quote Pin Huntsman Don't use 220-age. Run up a hill a few times until you feel sick or look at the end of a 100% PB effort for a 5k. Both will be a good indication of Max HR. Nice half WW. Fenners you are an enigma. My marathon PB was 84% average. Better conditioned runners would be nearer 89%.
Fenland (Fenners) Runner Sep 2017 11:08am, 6 Sep 2017 13,427 posts	Quote Pin Fenland (Fenners) Runner Hunts, what was the average for the initial ten miles, and conversely the last ten miles. Just wondering if I'm getting hung up on starting at 80+%.
