You’ll be able to pick up your race number on the morning of the event at the aid station/start line from 8.25am. The car park will be open 24/7 although the toilets at the visitor center will not open until 8am. Please do not arrive any earlier as we will still be setting everything up.

The route is a mix between compact gravel paths, roads and fields. Road shoes should be fine for this venue. Like all of our events going forward, we will be operating a bring your own bottle policy. We will not be supplying plastic cups or drinks receptacles at this event so that we can cut down on waste and do our part to help the environment. You will be required to bring your own water bottle, collapsable cup, or similar to the event. We will still have an array of liquids available for you to top up your bottles with at our well-stocked aid station!

The event will be taking place in a County Park that is open to the public. Runners will not have the right of way and we will need to be considerate to all the other users of the area, be it walkers, cyclists, families, etc.

We do not have any secure baggage areas on site but you are more than welcome to leave your bags at the base camp. Whilst we can’t guarantee that they’ll be safe, there will always be someone from Rasselbock around. If you are driving then it is recommended that you leave any non-essential items in your car.

We will have a fully stocked aid station at base camp full of all your favorite items, although if you are expecting energy tablets, gels, and supplements, you may need to bring your own as our aid station tends to lean towards the more “enjoyable fuel”. Imagine Fudge, cakes, cookies, and jelly babies along with all the savory alternatives.

Can I bring my own food and drink for the aid station?

You are more than welcome to bring your own food and drink to the aid station. We will have a separate table for these so please make sure that your bottles or items are clearly labeled so that no one takes them by accident!

There is a time limit of 6 hours for this event. This means that you need to have completed your final lap before the end of the 6 hours for it to be counted towards your final distance. Each lap will be 5.59km long with a total elevation gain of just 80 meters for each loop. This means that if you complete 4 laps you have run a half marathon, 8 laps, a full marathon and 9 laps or more will be classed as an Ultra. You can finish your event at any time within the six hours, and as long as you have completed one lap then you will be classed as a finisher.
