Hi Ady, how's it going for this did you learn anything about this one (beyond website info)? Interested in this one for 2015 or another year. I've been up to the high plateau of Teide NP in Tenerife before and its a strange and captivating place. And the idea of running across the island, predominantly to reach one very high point and then descend back to sea-level sounds like it could be a really gratifying and somewhat different to most multi-peak challenge ultra's.
