On the gun

Competitors begin their 5km or 10km run or walk in race five of seven in the Frontrunner series, at Jacks Point on Saturday morning.

Runners were advised they would quickly shed any thermal clothing.

Men, women, children - both running and riding in pushchairs - and dogs turned out for the races.

The final two races are scheduled for October 27 and November 24. The last race is a special half-marathon event.
