No, the only checkpoint is at the gate on the way to the trig. There will be someone at the trig to make sure everyone goes around it and also your fellow competitors would have something to say if you didnt haha. There is only one way back out and that is back through the gate so no need for a check of your number again there. As in all fell races anyone seen jumping walls will be disqualified. As long as you go through Ravenstor Cottages along the path and over the foot bridge you can start to climb. Be aware though some parts are so steep you would be quicker keeping to the path as you climb until you get past the bushes :-)
PS - there are two other CP - one at the gate over Hamilton Hill and one (plus 1hr cut-off) at Cressbrook Dale Water Cum Jolly.
There will not be as many marshals this year or taped markers except where there are safety or environment concerns. We didnt want all wandering around the countryside on the 1st running of it but this year it's bring your map and compass and know how to use it.
