The Treehouse 5k route is also a largely off-road route, as shown in the map below.  We use chip-timing by Rogue Racer, and all finishers receive an event t-shirt and a hand-made wooden medal.  Trophies will be awarded to the winners of each category.

The family bunny run course is around the recreation ground – two laps makes one 1km. Family runners can run as many laps as they like, and will receive a medal showing the distance that they achieved.

Getting there

Warm-up and start

There will be a pre-race warm-up, kindly provided by Simon Lord, for all those that would like to join in. This will take place near the start line at 9:45am, followed by a race briefing at the Start Line at 9:55am.  The 5k and 10k run starts at 10:00am.  The Family Bunny run takes place as soon as the 5k and 10K runners have cleared the field.

Toilets: There will be portable toilets located close to the start/finish on the Rec – please use these rather than the toilets in the Pavilion.  There is a disabled toilet within the Pavilion – if you need this, please enter through the front door and ask one of the helpers to direct you there.

Refreshments and activities will be available from 9.00 until 12.00. These will include bacon butties, egg butties, teas, coffees, cakes etc. Any money raised from the refreshments will also support The Treehouse School.
