I've had a couple of people ask how the marshals hundred went...the main event route will be very similar but with a couple of different checkpoints. The route is an interesting one and was carefully routed away from main centres of population and was well thought out
The first 12 miles or so is along disused railway lines, so there is a temptation to go very quickly and probably burn up too many calories. For train fans, enjoy the 2 miles or so of the famous Worsborough bank at 1 in 40, which is interestingly unrelenting even on foot. Imagine Gresleys U1 Garratt loco struggling up that with a heavy coal train and possibly 2 firemen working flat out ...but I digress
After Penistone the route twists about but navigation is easy and there are good views, especially looking down on Holmfirth as you approach. We had a small checkpoint at Holmbridge serving the most fantastic food but you will be going somewhere different.
After Holmbridge there is steady climbing all the way over Black Hill. The route was easy to follow, take care if the paving slabs are wet though. After Black Hill summit there is a long descent to Laddow Rocks above Crowden checkpoint. The route (Penine Way) follows the edge very closely. Pay extra careful attention on this section as there are steep drops over the side. The footing is good, but you must concentrate properly. For this reason the walk starts at 9am to get people through this section before dark. I traversed it at dusk on 30th April...you will get more daylight. If Crowden is lit you will see it about 1.5 hours before you get to it, which is a bit demoralising in some ways but reassuring in others. The descent to Crowden when it starts needs care because it is rutted and the ruts contain stones to roll your feet, so be careful. Consider poles, I did not, and in the dark, the air was thick with blue language.
After Crowden CP it's much easier and a good chunk is on the Woodhead route as we train people call it. Class 76's trundled over it until 1981, it was one of the first inter city electric railways..

The route description on leaving Crowden does a few things before you actually cut under the railway in a narrow pedestrian tunnel and then turn to gain the trackbed. The route description breaks this section into chunks talking about head to this sign there then something else here, when all that is really needed is something like "keep on the trackbed for about 4 miles (might be more, I am not sat looking at the Route description whilst writing this) until it ends by descending a slope and then you are in Dinting " where there's a bit further to go to get to the Scout hut. On to Hayfield, did that at night, was not too difficult.
The next piece took us on to Mam Nick which was a car park checkpoint. The daylight appeared en route. Take care to make the correct turn off the road on ascending from Hayfield, there's a turn to make and then you are back on an ascending road. I think it said keep going until you get to a white fence after a mile. This seemed to be longer, indeed some of the quoted distances did seem misleading but you need to remember I was doing bits at night so obviously the old brain function took a nose dive lol.
Our checkpoint at Mam Nick was rudimentary but the most fantastic food appeared. You leave and are thinking it'll be a big pull up to Mam Tor but it isn't and it's all on pitched path. Piece of cake, then along the spectacular ridge to Lose hill, the views either side were excellent. Our weather was a bit iffy but it was still good. Descend to the breakfast stop at Hope.
After our, not your, breakfast some wiggling about and an awkward grassy side ascent to a low ridge. With a bit of map work it can be avoided. Join a lane...there is a parallel enclosed footpath although the route description seems to ignore it. Don't know why as safe from traffic. The route then follows the river through many fields and eventually you are deposited at a fairly busy road. Counter intuitively the route reverses west and you swing into Hathersage from the western end. Hathersage will be your breakfast stop. Loads of walking shops if replacement gear and energy bars needed.

After Hathersage a long but gentle ascent to Stanage edge. The views make it all worthwhile. We were blessed with sun at this point. It was fab. As soon as you make the top, the route bizzarely descends again but you then run parallel to the edge and follow the track through rock and discarded, presumably defective millstones. Go right to the end of the edge, continue and cross the main road to the delights of Moscar checkpoint where all being well I'll be there to welcome you and presumably get comment " why didn't you tell us about...." And "wtf were you thinking about when you said that bit was easy etc". So I might be hiding 
The next part was easy to follow and the route description was fine. If you are like me you will be on the second night.
Leaving CP12 took us downwards then into a wood which I had some problems with. After crossing a railway, it talks about following a path that ascends. This path is not particularly clear in the dark and you may not see it. A bearing on the route description here would have been incredibly helpful but there isn't one, (yes I am a traditionalist [old f**t more like-Editor] without GPS or smart thingy on the walk) so man or woman up slackers. However, the instructions talk about keeping away from the RHS edge of the wood where there is a fence. A much wider set of paths ascend very gently to the left. I took these, but they are not the route. Find the centre path. Make a more rapid ascent and you will end up on a grassy track which cuts across in front of you. Turn right as per the Route Description Look out for the ruined buildings on the left and follow the track to the base of a pylon. Then on behind the pylon and cross about 7 fields by following their left hand edge. You will think I've got this section in the bag now...it is not .. and soon and then after turning up a wide industrial entrance and continuing I turned and entered woodland.

Great care and attention needed NOW. This is where I went about 3/4 mile off route. There is a choice of turns as you enter the wood. As with all woods on the second night this is where mistakes happen . I believe there was a choice of 3 tracks. The route description made me think I should take the middle one. It is me who was wrong, I needed to take the right hand one with the white gravel that was the width of a vehicle. Although you think the white gravel must be new and it must have been laid after the route description was written you are wrong and you need to be on the white gravel track. This is extremely important as in the dark you will have a lot of difficulty trying to find routes to get you back on course to find the dreaded clipper which lurks near a settlement at the top of the wood. If the instructions don't make sense and you see overhead wires you are on the lower woodland route like I was. Turn round and get back to where you entered the wood. Your OS map shows the route 627 but there ain't no route 627 signs to see...you actually are turning right on to the Eastbound 627 and follow that a short way. Ascend the white track, follow the route description and you will be fine. The section along the edge is quite slow in the dark but eventually you will find a gate and veer right, again it is some time before you make the ponds talked about in the route description.be patient. The route description is right. There's a paved tunnel next under the M1.

At either CP13 or 14 (you can tell it was the second night) we were assaulted by a gang of fish finger sandwiches. To say they were enjoyable would be an understatement. You might get lucky, it is a high mileage checkpoint, which means, in my experience, the food quality goes up sometimes to stratospheric levels.

As we neared the checkpoint 15 a body wagon operating in the style of the child catcher from Chitty Chitty Bang Bang kidnapped 3 of our merry band of 5 from the roadside. Your correspondent and his trusty colleague declined the invitation and we made haste to the checkpoint. On arrival we were faced with tales of gloom and doom about how the 48 hours would be up and it would be best to sack it now, given the CP was on borrowed time. Our sweeper was still happy to continue and although tempted, I did not say "do you know who I am" [surely an excessive ego based-comment-Editor] ,or, "I have done 28 of these things you know" just that I was still up, after 90 miles to complete the distance and wasn't bothered about the certificate. This was a bizarre concept for the marshal who let us on our merry way. After a mile or so warming up again, it was time to see if there was anything in the tank and turn the heat up. Fortified by the double coffee from the CP and the increasing daylight, I turned the gas right up and went into the long extended loop around Wentworth Park to the clipper and on to the CP at Elsecar. Although you pass one or two signs indicating less to Elsecar you need to follow the route and get to the clipper, which is just before the route folds backwards to Elsecar. The terrain is all easy, grassy, mostly gentle gradients. Take heart from the fact you are increasing miles for little overall effort. We left the previous CP 35 minutes down and roared in to Elsecar 15 min early, averaging 4 mph on the penultimate section of 6 miles ...I will be dining out on that one for months.
A final push for home, I am glad the sweeper was with us as just about every fp was called the Trans Pennine Trail and we seemed to be going all over the place. Finally we neared the school and a rapturous reception awaited. Many did not think we would do it, but there was 27 minutes to spare. The taste of victory was sweet as they say. It had been a memorable trip and I need to spend more time training ..see me as the teachers used to say lol.
