The hospital charity where I work have just emailed me to say they have a last minute London Marathon place available due to injury, and do I want it? I had till midday to respond so have said yes 
Currently I run around 25-40km a week, broken up into 2-3 5km runs and 1-2 10-15km runs depending how I'm feeling. I did a half marathon in just under 3 hours in May which went okay, but haven't tried it since.
Marathon is 3rd October so I have 43 days to train, is this doable? And does anyone know of any good training plans? Hoping people with marathon experience can help here! Thanks all
