Hurray! The pins and cast came out/off my wrist today, and it's 5 weeks 2 days till my Alps MTB trip. After some online research, i think to get fit i just need to put on a questionable set of tracksuit apparel and run around the scruffy/down-at-heal parts of town pretending to "airpunch" everything yeah??
(the bad news is, my wrist currently moves only about 20 deg...........)
