ATW Bison Duathlon

The Bison Duathlon is back... bigger and bolder than ever!

  • Booking essential
  • Admission applies

This fantastic event starts at the our Visitor Centre, with the scenic Chiltern Hills forming your backdrop.

You have a choice of the two lap Bison course, or the one lap 'Baby Bison'.

After a 13(or 6.5)km trail run around Dunstable Downs, you'll swap your trail shoes for bike shoes and head off through the Chiltern Hills for a 22km cycle loop with amazing views of the surrounding areas. The full Bison completes two laps, while the Baby Bison 'only' completes one.

If you've got anything left, both distances finish off with one lap of the challenging 6.5km run route.
