Aid stations are located at roughly 14.3 km, 28 km and 37.2 km and include water, cola, electrolyte drink, gels, chews, crisps, sweets and fresh fruit. Toilets are available at the event base and at all three checkpoints. The event uses chip timing and provides live results, course-wide medical support, bag drop and free onsite parking.

Runners must be at least 20 years old. The field is limited to 250 runners and the overall time limit is 8 hours 45 minutes.
