I'm kicking around the idea of riding the Curadmír in the spring of 2015 (almost 600km over 3 days across Northern Ireland), a ride that would obviously have a lot of elevation changes in it (~2000m/day). A year is a lot of time to prepare for it, except for one small problem.
I live in the Netherlands.
A country almost entirely flat and almost entirely below sea level. The biggest hill within 250km of my home is a highway overpass.
Short of getting on a train to the Kapelmuur every other weekend from October to May, how would you recommend I train for riding hills without, you know, riding hills?
