Mainly running now, which I restarted a couple of months ago after a two year period of only really cycling (my legs haven't forgiven me yet). I'm really enjoying it as I think it is giving me better overall fitness than cycling. Also get climbing (indoors at this time of year) a couple of times a week which helps my flexibility/balance etc and try to fit in some hill walking/scrambling when I get the chance. Would love to be able to do yoga again or pilates but I just can't fit in classes, they all seem to be on at the wrong time.
