Can you identify the club - Sheffield/Peaks?

I've not got much to go on other than to say that there was a group of around 20 heading towards Hathersage from Hope in the Peak District at about 11.45 today (Sat 11th). I've seen them a couple of times and they appeared to be going pretty quickly, perhaps race orientated. I didn't spot any jersey colours to go on. Both times I've seen them a relatively small bloke was doing the work at the front and dropping one or two.

Bag of crisps for the person who can convince me they know who they are.

Thanks
