Ultra Marathons in Powys, in context
Ultra marathons make up most of Powys's racing on Verus — 8 of 12 races, or about 67%. If you run this distance, this is a well-served county.
The dates are spread across 6 months of the year, which gives real choice about when to peak rather than forcing a single date.
Only one of them publishes an elevation figure: The Beacons Ultra, at 7,408ft of climb. Where an organiser has not published one, this site says so rather than estimating.
