These Ultramarathon runners especially Dean are extremely fit athletes but would find it difficult or near impossible to stay with the likes of Billy Bland or Joss Naylor in their heyday.
Billy Bland still holds the Bob Graham round record in just under 14hrs or 13hrs 52min to cover 72miles over 46 of Lake Lands finest peaks.
Joss Naylors every Wainwright peak (all 214 of them) in just under 7days or if you take from start to finish Moot Hall to Moot Hall in 7Days 1hr and visiting every single Lakeland lake or water in just over 17hrs beating Billy Blands incredible record by an amazing 9hrs.
Ultramarathon running on a fairly flat course is hard enough but when you consider to visit every single lake in the Lake District involves a distance of 141miles over some of the hardest terrain in the Uk all in under 18hrs now that requires stamina that very few top athletes can sustain.
Do not forget Mike Cudahys sub 3day Pennine way record and two runners have now run back to back Pennine Ways in under 9days.
That's 532miles of almost continuous running.
There's Ultramarathon running and those select breed of runners whose regular training runs involve running distances in excess of 146miles in one go as Billy Bland used to do back in the early 1980s when he would do back to back Bob Grahams just to train for the likes of the Ennerdale Horseshoe.
The UltraDistance Fell Runners are possibly the toughest runners of all.
