On 12th April I spent time on the treadmill at the National Center for National Centre for Sports and Exercise Medicine at Loughborough University. I met with Professor Laura-Anne Furlong and Research Associate Mathew Black who will be studying my biomechanics over the 5400km. They completed some blood tests and generated a 3D video of my running (see below). The blue loopy shapes indicate the position of the markers Laura-Anne attached to my body, the ones highlighted are the ones on the outside of my little toe, the outside of my ankle and my knee (which are used for calculating ankle angle). Humans don’t do things the same way over and over so you can see subtle changes between each step. The graphs on the right are the position of these markers in 3D space.
