David Lee discovered this photograph in his fathers ( who was a sapper in the Royal Engineers) photo album. He suspects his father may have taken the photograph but has no evidence to back this up. It is very probable the soldiers were stationed at Clipstone Camp but at this stage we can only assume this.
I have found the article below in the Nottingham Evening post which tells us a little more about this record attempt by Pte Annett of the RAMC.

SOLDIER’S 24 HOURS’ WALK.
An attempt to beat the world’s hour 24 walking record of miles 131. 500 yards, was made on the Forest Town Athletic Ground, Pte. Annett, of the R.A.M.C., a well-known professional pedestrian. Annett commenced his long walk on the cycle track, at 7 p.m. Friday, but the conditions were so adverse, that although he finished strongly, his total for the 24 hours was only 114½ miles
