One of the major events Dark & White organise is the annual two day Rab Mountain Marathon. Run under FRA (Fell Running Association) rules and guidelines this is a classic mountain marathon/navigational challenge in the mountains for solos or pairs; all courses are set up on a score basis with a time limit therefore fitness, event strategy and navigational skill is the key to success. Competitors have to be self sufficient for the two days; there is a remote campsite on the Saturday night. Rab (www.rab.uk.com) provide a superb range of prizes.

Each Autumn/Winter D&W organize a series of shorter mountain marathons (mini-MM's) in the Peak District - these are 3 hour events aimed at testing both competitors legs and brains. Each entrant is supplied at the start with a bagged colour OS map extract over-printed with all the required event information.

The aim of the events is to navigate your way between a series of checkpoints and collect as many points as you can in a specified time period. Armed with your map (and your brain!) it is up to you to decide the optimum route based on your fitness/ability. Each checkpoint has a score, and generally the ones which are further away and more difficult to get to are worth more points.

If you take longer than the allotted time you are penalised some of your hard earned points. Those taking part can either enter as a solo or as a pair in various classes; a wide range of abilities always take part. Event timing is electronic by SPORTident, see www.sportident.co.uk for details.
