The Fellsman, Yorkshire
With ultra-marathons becoming expensive corporate events, thank goodness for the old school Fellsman, which has been organized for 53 years.
The route 61 miles long and covers 11,000ft of rugged Yorkshire Dales moorland. Most of the route is over private land, so navigational skills are crucial. There are ‘chop times’ and runners must team up for the night section.
