DH is training up for an insane run in March- the Grizzly in Seaton, 20 m of up and down cliffs and through the sea and mud etc... I realise I've left this late but I want to get him an iPod to help him with his training as he's hitting a bit of a wall at times. What sort do you think? Would a nano be the best thing? What about a halter thing for it? Also I need running music suggestions! Any help gratefully received.
