TR I can relate to that as well. I tore my calf muscle so bad it meant an hospital visit but as much as I would like to say otherwise I just love running. I enjoy the bike but with running you can spend a lot less time getting fit and adjust your route literally on the hoof, sorry about that.
Did a short run earlier today and guess what calf muscle feels sore now. Looks like the next few days I will be back on the bike then.
Ouch! Nasty, isn't it! Worst part is limping home afterwards. I was gutted at the time, TBH, because I'd got my minute mile down to just over 6mins on the previous run, over 5 miles. Was aiming to try a 1st competitive half marathon but pushed it a bit too hard. Thing is that I've sold my car now, so I have to ride in to work because public transport would take twice as long to get in.
Having a week off work in Feb though, so might knock out a few runs and give the cycling a short rest. My beautiful orange Adizero's cry in my general direction every time I go past them on my bike...though I can't really tell if they're tears from laughing so hard at my injury.
Hope your calves heal up nicely. I heard that peanut butter on a bagel immediately after a run is the best thing for it, if that helps.
