‘Horrendous blisters’: Retired UK banker, 65, attempts to run 200 marathons in 200 days

Steve James, from Devon, hits halfway mark in circuit of Great Britain's coast as scientists monitor impact of extreme feat

The first fortnight was tough - terrible blisters, a flare of gout that needed a visit to A&E and the rapid realisation that running 200 marathons in 200 days around the coast of Great Britain would not be a walk in the park.

But Steve James, a 65-year-old retired banker from Devon, has found his feet, and on Thursday reached the halfway mark - an average of 100 marathons in 100 days.
