When asked what it was like to experience some of this fame, he answered "it's pretty mean aye".
As well as the interviews, Robertson-Barnes was recognised by the Crocs brand and has been sent a few pairs of the rubber sandal as recognition for the bizarre feat.
Robertson-Barnes said he would run another race in Crocs and even considers starting an all-Crocs running club.
He says "you don't need the big name running shoes like Nike and Asics to run a good time. "Just remember to wear socks with the Crocs".
Before the race, he realised there was no place to put the transponder - the small timing device attached to the shoe - and so slipped it into his sock which resulted in a blister at the race's end.
As for his next contest, Callum is not sure but he say he often hikes in his Crocs and will continue to do so in the future.
