rules.

01

Six point seven kilometres.

Every loop is the same. 6.706 km around the reservoir — A mix of walking & mountain bike tracks.

02

The Race Director flips a coin.

Before every lap start, the Race Director flips a coin at the kennel. Heads — clockwise. Tails — anti-clockwise. You don't know which until you go, and you don't get to choose.

03

Every hour on the hour.

The bell rings at the top of the hour and you go. Be back in the kennel before it rings again, ready to head out for the next lap. Late by a second? You're out.

04

Last person standing wins.

There's no podium. There's no time. There's no second place. Only one runner finishes — everyone else is a DNF.

05

No assistance on course.

Crews live in the camp. You go alone. You come back alone. The event organisers may put wee treats out on the course, but it will be a surprise at the time.

The same 6.7 kilometres. Forever.

Clockwise: out the gate. Down the track. Through the kiosk. Over the stream. Graded walking track for nearly 3 km, then single-track mountain bike for 1.5 km, then a gentle downhill to the finish. Keep the lakes on your right going clockwise. Anti-clockwise, keep them on your left. That should stop you getting lost.
