Race format and race information
Distances:
- 5 km
- 10 km
The event includes placegetters prizes, a drink station on the 10 km course, water and fruit at the finish area, and a coffee van on site for purchases. TRSA will use manual timing: finishers cross the line with their bib visible, take a numbered pop stick from the marshal, and hand that pop stick and their bib to the results marshals for recording. Walkers may take part in the short course only. Participants should bring their own hydration vessel and a mobile phone; basic first aid items and appropriate clothing are recommended. The event operates a strict course closure and participants who do not finish before the course closure will be recorded as DNF. Visit the organization's website for the most recent information.
