Taking place on Sunday 11^th September, the dog-friendly challenge offers walkers a choice of routes through the stunning Chilterns countryside. Walkers choose one of four available routes and seek sponsorship to raise vital funds for Rennie Grove’s specialist nursing care.

Starting from Princes Risborough School, the route options for the challenge are:

• 6.5 mile linear route which tackles Whiteleaf Cross and Coombe Hill
• 8 mile self-guided circular route taking in Whiteleaf Cross
• 10 mile linear route which gives walkers the opportunity to complete all three peaks (Whiteleaf Cross, Coombe Hill and Ivinghoe Beacon) with a bus journey between Wendover and Tring station taking out some of the miles
• 18-mile linear route is the complete route from Princes Risborough School to the top of Ivinghoe Beacon walking all three local landmarks

All routes include a bus ride back to the start at Princes Risborough School.

Tickets for this family-friendly event cost £15 per adult (16+) and £7.50 for children (5-16) with under 5s free on all routes. Family tickets are available (two adults and up to four children) for £40.
