Cassiobury (was Highfield Park)

28 May: We’re pleased to say that pre-registration is now available on Please do so if you can, it saves both you and us time on the day.

To avoid a clash with a football tournament in Highfield Park, we are running the event at Cassiobury that was postponed from 3 March because of snow. We are not expecting snow in June.

Cassiobury parkland

Runnable parkland with some wooded areas, some with significant undergrowth. The undergrowth was very low for the originally planned date of 3 March, but it will be higher in June.

Full leg and torso cover required for Orange course and above.
