Update on the foot, since people have been asking :)
Has slowly improved from day to day, generally just a dull ache while walking - being on my feet for a few hours every night since hasn't been the best recovery.
Last night at ARK I stood awkwardly on it and was plagued with acute pain for a few seconds... then, it felt really good. Weird.
So, resting the next few days totally should do the trick, maybe I'll make it to the first O-Cup race.
