More interesting info from this Telegraph article.
Sounds like he's only been a runner for 2 years. Sounds like he started running due to a challenge from his wife to run a marathon after watching the London Marathon in April 2014. So it's not like he was a fast runner several years ago (sub-31 10K, etc.) and now is slower as an ultra runner. Sounds like the PR claims for 5K, 10K, half and full would be sometime in the past 2 years. If so, then where is the data?
Also according to the article, it sounds like he's driven his family into severe poverty with his running addiction. So is he trying to make a living by becoming a celebrity ultrarunner? Another Dean wannabe?
