Great Britain 100km rankings 2025
100km, along with 50km, are currently the only two ultra distances recognised by World Athletics for record and ranking purposes.
While trail races at distances above 50 miles continue to flourish, road 100km events in Great Britain are few, with the annual Anglo-Celtic Plate Home International providing the best domestic competition.
Men’s 100km Rankings 2025
2025 saw the continued improvement of Henry Hart and Kelsey Price to record the fastest 100km times of the year
Belgrave Harrier Hart, with his 6:37:18, was a clear lead in this year’s mens rankings. The Mallory Park course for this year’s Anglo-Celtic Plate was a traffic-free circuit usually graced by motorcycle racing. It was a challenging loop with two fairly steep but short inclines on each lap. It makes Hart’s time all the more impressive. Sean Dixon was the only other British Male to break 7 hours with his 6:56:13.
