Public Transport – The nearest major train stations are Nottingham and Derby, although the nearest station is the small Langley Mill. Both Nottingham and Derby have bus services to Heanor, although their services do vary at the weekend and it is always best to check the timetables before booking.
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.
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!
Organiser's description
We're back in April celebrating the Butterfly's fluffy friend, the moth. The Luna moth probably being the most iconic.
The aim for our events is to organize races that I would want to take part in, so you can expect amazing support, the best medals and goodies, and a small group of runners that is never any more than 150. Think of it as a small group of friends and family all coming together for an amazing day of running!
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 5.45km 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.

Rasselbock Running
Here at Rasselbock we love organizing events that we'd want to take part in ourselves. Be it with unique and different styles of events that haven't been seen before, to simply run and submit events with some massive medals! We organise in-person events around the Midlands with a focus on fun, participation, and have no set distance. The majority of the events looped courses with a 6-hour cut-off window. Complete as many laps as you'd like, although you need only complete one to be classed as a finisher! We are a new small company and every person who signs up feels like part of our little family. We'd love to have you on board. Eric + Jonathan
