Starting at 64°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Light winds shouldn't be a major factor for pacing. High humidity (88%) will make it harder to cool down through sweat — increase fluid intake accordingly.

About the Farnham Pilgrim Half Marathon

The Farnham Pilgrim Half Marathon covers 21.1 km of multi-terrain, largely off-road paths along the Pilgrims' Way and North Downs Way through the Surrey Hills National Landscape. It starts and finishes at Myrtle's Courtyard on the Hampton Estate in Seale, the same race village the marathon uses. Wet weather often leaves the trails muddy, so it runs as a trail half rather than a road race. It takes place on the Sunday of race weekend.
