What is the Sea2Summit Challenge?

What is Sea2Summit
Because you've not done it until you've climbed from Sea 2 Summit.... The Sea2Summit challenge was dreamed up by Dave Talbot & Chris Newton-Goverd, "our idea was simple – start at the sea and finish at the summit!"
This website is host of all the current Sea 2 Summit challenges with details on how to complete them and submit your results to the "Wall of honour". The first challenge completed involved linking up a huge geological ridge feature that rises all the way from sea level to the summit of the Bernia mountain on the Costa Blanca coastline of south east Spain.
