Keeping fitness when not running

goji

So now I'm down with plantar fasciitis, what should I do to keep fitness that I gained in the HM training? Went roller skating last night but it turned out painful for the PF affected foot. Swimming should be ok but I'd like to do something else as well. Cycling and general gym seem ok? Circuit clas probably would include some running so I should probably give it a miss. Anything I should avoid in the gym?

i used it as an excuse to do more on the bike, mine happened in dec when we had the snow though so i ended up on the turbotrainer a lot.

Thanks Marc. Went for spin class today, totally wiped out but foot not under strain apart from hill climbs
