Running speed for the Kentmere Fell Race

We went to watch the Kentmere Fell Race. It is 19.8 km long and our competitor took 2 hours and 5 mins. That's an average speed of 19800 metres divided by 7500 seconds = 2.6 metres per second. The new GCSE syllabus says that you run at about 3 metres per second. I think given the terrain that we have seen a very impressive performance!
