There will be four distances on offer at the October 11 event, including a half marathon (21.1km), 10km, 5km and a 2km run / walk.

The three longer events will all start early on Sunday, and Forbes Running and Triathlon Club recommends people register before the day.

All half marathon participants will need to register online as that race starts at 7am. Registration for other events must be completed before 7.45am with the shorter runs to start at 8am. Race packs will be available to collect on the day from 6am.

Forbes Running and Triathlon Club spokesman Nick Field said online registration by most of the participants will ensure the events can start on time, before the mercury begins to climb.

Those who who register online prior to the event are also eligible for the early bird specials, which end midnight, October 10.

Registration costs are $50 for the half marathon, $25 for the 10km run, $15 for the 5km run and $10 for the 2km run/walk. Cost for all children aged 12 and under is just $10 for each event.
