About the event Whether you are looking for your first ultramarathon or ready to move onto to something a little more challenging Race to the Stones offers three beautiful routes to test your fitness whilst raising vital funds to support our patients and amazing NHS staff. Day One – Thames Valley 50k Starting in Lewknor, the Thames Valley 50k presents a varied and scenic route that is steeped in history. Crossing England’s longest river at the halfway mark at the ancient twin villages of Goring & Streatley, the route then heads back up onto higher ground, culminating with a triumphant climb towards our iconic Lattin Down basecamp finish line. Day Two – Ridgeline 50k Sticking to higher ground throughout, the Ridgeline 50k at Race to the Stones is an ideal choice for your first ultramarathon. Passing through a surprisingly isolated stretch of Southern England, you’ll enjoy dramatic views of the vale to the north before finishing alongside the full 100k at the iconic Avebury Standing Stones. 100k Non-Stop or Over Two Days Britain’s oldest road, the Ridgeway, follows the same route over high ground used by herdsmen and travellers since prehistoric times. Explore a remarkably isolated and unspoilt corner of Southern England through some of its most ancient landscapes, finishing by the 5000-year old Avebury Standing Stones, a UNESCO World Heritage site. Want to Break It Up? You can complete Race to the Stones 100k over two days, staying overnight at our iconic basecamp halfway. What's included in your entry?
