SN Trophy and SEL Event at Frith and Windmill Hills
2025-11-30
Southern Navigators welcome you to the 2025 SN Trophy
Celebrating our 60th anniversary year, Southern Navigators welcomes you to its annual Trophy event. This year we return to Frith Hill, with longer courses also using Windmill Hill. Frith Hill offers fast running in woodland terrain interspersed with a complex path network. Contrasting this, on the eastern edge of the Chobham ridge, Windmill Hill offers steep slopes with intricate contour detail and numerous pits and knolls.

Terrain
Frith Hill offers fast running in woodland terrain interspersed with a complex path network. Contrasting this, on the eastern edge of the Chobham ridge, Windmill Hill offers steep slopes with intricate contour detail, numerous pits and knolls. Courses from Short Blue upwards will use both areas.
Location
Car park entrance
Starts and Finish
Courses close and controls will be collected in from 14.30. Please choose a start time that means you will be back and downloaded by 14.30.
Start times are between 10:00 and 12:45. Your allocated start time can be found at Frith and Windmill Hill event web page
There will be a near and far start with courses from Short Blue upwards having a 1600m walk to the far start. The near start will be 300m from the car park. There is no climb on either route. The route to both starts leaves the car park at the north eastern corner.
The Finish will be in the Assembly area
Courses
A suite of courses from White to Black are being planned. Under 16's on courses longer than Green will have an unmarshalled road crossing and some minor estate roads to cross on the way to the far start and up to 2 quiet estate roads to cross before the timed-out marshalled crossing on the course.
