Other Race Information

We will have a secure area where you can leave your baggage. We recommend you bring as little baggage as possible. Your baggage tag is attached to your race number, you simply tear it off and attach to your bag. To collect, show your number to the baggage tent staff and they will help you find your baggage.

There will be portable toilets for you to use within the event village.

There will be water available on every lap of the race, and there will also be water available at the finish. We have also ordered some flapjacks and bananas for when you finish :-)

There will be marshals all around the course as well as km signs and arrows. The course consists of laps around the lake and will involve 1 lap for the 5k, 2 laps for the 10k and 4 laps for the Half Marathon. Please be aware that there will be spectators and members of the public using the park.

You are free to wander around the lake so you can see where the competitors will be running. It is lapped so you will see them on numerous occasions.

Results will be available on after the race.

We will have a photographer taking a few snaps of the race and they will be on our Facebook page after the race so be sure to check it out and see if you can spot yourself.
