well, A friend of my by the name of isaac sim recently completed a challenge of his which involved him walking the length of hadrians wall in 24 hours, so thats 80 miles
Isaac is the one in the middle, epic haircut or what? 
He completed this epic walk along with two friends for the army benevolent fund, more info on them here, they’re a really worthwhile charity 
Here is the first half of the write up, isaac hasn’t finished writing it yet, too tired
We did it !
After we’d driven to carlisle, we started at 10:32AM on monday the 31st of may on the shore of the rural village bowness. the team, fresh for anything Hadrians wall could throw at us was raring to go. At first we had a minor issue, we hadnot yet purchased a map of Carlisle and surrounding area, so our navigator isaac, made up the route to carlisle only to find out that the rather large mound of earth running parallel to the road was infact the wall itself 
We hit carlisle at approximatly 12:30 - 1:00 ish where we had a much needed replen of water, a quick intake of food for energy and a few photographs. We had 20 mins stoppage time there. We tried not to include this is the actual 24 hours itself but it was hard to think that this wasnt in some way a different interpretation of the rules, so we ploughed on as soon as we could 
The first disaster struck just after carlisle almost as soon as we’d left the city. There was (presuming i have the details right at all) a motor show, where people could bring along a motor, be a car or infact just an old engine mounted on a trailer, situated in Rickerby park. The entire park and surrounding roads were cordonned off for the event classed as a no acccess route. What was worse there was a fee to pay to get a wrist band to enter the show grounds. Isaac wasnt too happy about having to waste alot of time and extra effort going round the park because of issues with navigation, restrictions including a river, the show itself, and not wanting to go back towards carlisle. So, in true Isaac fashion we walked through the gates, past the unmanned ticket stall and continued through the park. Sorry to anyone this may have annoyed, but at the time it had to be done.
Unfortunatly, James had been experiencing some severe discomfort in his chest, combined with the enormous blisters on his feet cause by german para boots. This ultimatly led to him being unable to walk. As a team, we came up with the decision to allow james to rest on the support vehicle and would be able to join back up later on. This was considered to be within the rules. Anything was, aslong as someone was walking the wall at all times. 
Without james, the team was down to two boys. At first we made up some unbelievable distance averaging a little more than 4 miles/h. Over tarmac roads and on a gradual downhill streach, cadets well renounded ‘Colts Canter’ competition came into effect. Walking as fast as you could on an easy part of the route made up alot of ground we had lost in the heat of the midday sun. Before long, at approximatly 4:00pm, Isaac and Ryan were at Birdoswald roman fort. James’ feet were in worse condition than first thought, he was unable to walk. : /
it was nearing 6 or 7PM and Isaac and Ryan had blitzed through to walltown quarry. Between Birdoswald and Walltown Ryan had developed the mother of all blisters on both feet. Isaac and Ryan stopped at th milecastle just short of Walltown where we checked the blisters. “As soon as Ryan took his fist boot off, i could smell the toe jam. So i pulled put my first aid kit and opened the roll of equipment i had. On looking inside i found i had one last blister pad. A blister pad which was for me when my feet started to die. i looked at the bleeding hole in ryans foot and i said here bud, have this. The blisters were bigger than a 50 pence piece, they were about the size of the base of a coke can, and deeper than id seen before, even in my cadet career. I pulled on some ruber gloves and treated his feet. Im glad i dont get phased by the smell of rotting feet ;)”
When we got to walltown quarry, Ryan also couldn’t actually walk. Even the littlest blisters can stop a man in his tracks, never mind these bad boy blisters. As we stopped for 30 mins to have corned beef stew for tea, we had a team discussion. Ryan and James couldnt walk, they wanted to and they would have tried if they’d been asked. But they physically couldn’t walk. Isaac being the only member of the team who had not had blisters was faced with a decision. The minibus had to transport Hannah, Isaac’s sister back to cramlington as she had to sleep, not be in the mad minibus all night. The boys could no longer walk at all. This was the end of the road for them. As unfortunate as it was, through no fault of their own they had been hampered by sun stroke, exhaustion, dehydration, blisters and sores. Non of these could have really been prevented effectivly at all. The decision was for the team to make. Ryan and James could no longer walk at all. They could go back home to rest over night, a well deserved rest. This would mean Isaac would have to walk alone and unsupported for a while in the evening over the crags in poor light. The most dangerous part of the journey in fading light by himself.
It was decided, Ryan and James travelled back. Isaac made his way to the next RV - housesteads alone.
