Organiser's Description

The Cowman, Longhorn, Calfman & Stampede Duathlon returns for 2020, with four distances across our tried and tested routes in the beautiful Emberton Country Park, in Buckinghamshire. For those who have completed the triathlon version, the run and the bike in the duathlon are just as challenging!

If you want a tough race then look no further! The Cowman is the toughest of the four distances on offer, with a 21k run, followed by a 90k bike and, to finish you off, a 10k run. The 2020 event is also hosting a qualifier for the British Triathlon GB Age-Group Team in the Standard race.
