Hi all. Four major developments in this case:
1) After I gave them a major kick up the backside for the runner having a physiologically impossible low heart-rate, he suddenly went up to 145+bpm 40% of the time on day 13. From 0% for the previous four days. However, he didn't like that and the rate of 145+ is now nose-diving again, and the -120bpm back on a sharp rise. All so frustrating and their pace remains world class. They averaged sub 7 minute K's on day 13! Totally unheard of for a challenge like this.
2) I have analysed the runner's 48 marathons in 30 days challenge he did in 2021, and this too was highly irregular. He returned a "clean" heart rate reading for an appalling 10 of the 48 marathons. The rest were either a data "freeze" or simply impossible. Ie 5 minute Ks at a 110 heart rate.
3) They have started to become extraordinarily abusive to me, posting three videos online and calling me a gremlin, a maggot and much more, with constant swearing. Oddly they based their initial rant around my email weeks ago just gently saying that about 40 miles a day would be a realistic, but still very tough target. Hardly polemic.
4) Some have written to me to say I may be placing too much emphasis on the reliability of wrist monitors, but all I would say in that out of over 1,000 runs studied, the only ones with corrupt data anything like this, are ALL by Goodge: 12 at Jogle, 26 at 48/30, and now 13 more here. No-one in the history of the sport goes from 165bpm to 105s but maintains the same pulse. If so, who? I asked this of my staunchest critic and he replied, that he "may struggle," to find examples. I'll second that.
I have consulted the National Library of Public Medicine who have done a study of the accuracy of wrist based Garmins vs electrocardiograms, and they found this:
"Results: Both devices showed a low mean absolute error (1.16-1.48 bpm for Apple and 1.35-2.25 for Garmin) and mean absolute percentage error (<1% for Apple and 1.16-1.39% for Garmin) in all intensities."
Thank you for keeping this matter relevant. What's going on is appalling: trying to raise over half a million bucks, whilst clearly not doing the event properly. And instead of engaging with my concerns, they just troll me with disgusting abuse. They are of the opinion that I am a lone wolf. They are mistaken.
He is a quarter done, for a 60 day projected finish. Bruce Tulloh's fine British record of 65 days from 1969 could well fall to an unknown runner with no pedigree and clear and obvious irregularities. This would tarnish Bruce's legacy and be a huge miscarriage of justice. But the graver problem is raising money for Gofundme off a hoodwink.
