Who is this guy and why am I on his blog?

Matt is a London based, 5 x Marathon runner. He documents his every running move, much to the displeasure of all those on Instagram who are trying to look at photos of beautiful dachshunds and make up tutorials. In 2014 his own body made an attempt on his life which led to a year long squabble with testicular cancer. Luckily he's been in remission for 4 years now. He also talks in third person, what a loser.
