So Rob created this domain name in 2011, years before he became MarathonMan: http://bgp.he.net/dns/runwilduk.com#_whois
He used runwilduk.com before he registered his marathonman domain: https://web.archive.org/web/20141218045052/http://runwilduk.com/
I wonder if Rob scrubbed his facebook for any references to running before April 14, 2014. I don't see mention of parkrun 5Ks which according to Powerof10 he ran many times. If he removed all references to running before April 14, it would make him look like couch to instant marathoner.
