Gear for this race

Chosen for 80 km of trail.

Trail Running Shoes 80 km of trail — cushioning that is still there in the last quarter.
Race Nutrition 80 km of self-supported fuelling between aid stations.
Hydration Vests Flask capacity for 80 km, without the bounce.
Headlamps 80 km almost certainly means running into the night.
GPS Watches Battery life first — a 80 km day outlasts most full-GPS modes.
