An Omnium multi-event option combines a long distance race (6 km, 10 km or Half Marathon) plus a 100 m sprint, a 1 km middle distance and a hill climb. The marathon has a 3 hour cut off to start lap two. Omnium entrants using the Half Marathon as their long event must finish in 3 hours 15 minutes to be ready for the next Omnium discipline. Other distances have no formal cut offs. Pure walkers are not admitted; mixed run-jog-walk is permitted.
