Inspired by the motivational athletes and determined students participating in AQA Unlocking Potential this year, Helen Stacey is walking 50km across the Ridgeway (Oxfordshire to Wiltshire) in the Race to the Stones.

Ending up in Avebury, this challenge is the most popular UK ultra-marathon and includes a sneaky elevation around mile 20, just when the legs would prefer a well-earned rest! This will be Helen's longest and hardest challenge yet so your support will help with all those hills!

All your donations will go towards the students' fantastic work setting their own challenges, overcoming adversity and finding success.
