> I have heard from friends who've done Glen Coe Skyline that you're queuing on Curved Ridge and passing people isn't really on. To me this turns it into a bit of a gimmick for most competitors.
Yes, if you aren't one of the first ones up the ridge, then standing in a queue during a race can feel very contrived. The difficulty with Curved Ridge is that although there is space to move around, it isn't especially safe to do so, as there is a lot of loose rock and scree on some sections. The queue builds up leading up to the crux ramp and the steep wall below it, although you could bypass it by say, scrambling up the gully on the right, it would create a horrible rockfall hazard for everyone below. Once you're above the crux though it's easy to spread out a little bit and there's plenty of space to move around people.
This is one of the main safety aspects that the organizers have to prepare for, by scouting and marking the route in advance and having people dotted along the ridge to ensure runners stick to the designated route.
As Harry Jarvis mentioned, this was one of the factors that led to the change in the race start-point, moving it from Glen Coe ski centre to the race HQ in Kinlochleven. This means runners have the climb up the WHW out of Kinlochleven, and the descent of the Devil's Staircase to do before they cross the road towards the Buachaille. Unfortunately last year's race was shortened due to bad weather, which meant that runners were able to increase their pace on this early section, and the crowd didn't get as spread out as they might have done normally.
That brings me to another safety point worth mentioning. The GC Skyline has a good weather route, and a bad weather route avoiding Curved Ridge and Aonach Eagach. Last year, there was rain and 100kph winds on the forecast, so it was obvious they would decide on the bad weather route. However, the organizers made a remarkable decision to use the bad weather route but add Curved Ridge back in, as the wind direction meant it would be sheltered from the worst of the weather. They were right, and the climb/run/queue up the ridge was in pleasant weather, whereas the run across the summits was a total blasting of wind and rain whilst trying to get one's jacket out without it blowing away!
This kind of decision required excellent judgement on the part of the race organizers and safety advisers, and I for one think they made the right call. The Aonach Eagach would have been desperate in those conditions, but Curved Ridge was safe. It's remarkable that in our 'health and safety' orientated world they were able to alter their plans at the last minute to include a section of the route deemed to be 'higher risk'. It made the race more enjoyable and satisfying for all the runners and was a great compromise between the planned good and bad weather routes.
