I hope the injury clears up quickly. Good idea to have a back up plan. There's always next year or other races to go after marathons if you have injury problems. Good luck at the physio.
Surprised you could feel anything other than wet and cold after Stockholm though!
While you're injured I'd drop any thoughts of going for a time. Get back running injury free, see how your training goes after that and base a time goal off your training closer to the race.
As you say there are plenty other races to go for a specific time.
Sarah - The the medals tend to use the same design, but the marathon medal is larger.
Kenno - Good luck! Fingers crossed it something easily sorted.
RunBaz - Welcome to the forum.
RR - I'm sure the stamina will return quickly. I always feel the first few long runs after a bit of a break always seem really tough, but then you start to get back into the way of it.
