In order to complete the Welsh 3000s Challenge you are required to have been at the top of all 15 of the mountains over 3000 ft in Snowdonia National Park Wales within the space of 24 hours, without using any form of transport. The length of the total route is about 30 miles, and this is a tough non-stop trek yet the challenge will be paced with trained mountain guides, support staff, rest stops, food, medics and much more to ensure that all who take it on have the best chance of making it to the finish line; 24 hours and 15 summits later!
