I've signed up for the Paris marathon, and the Edinburgh marathon (where I live, and a fast course) is 5 weeks after that.
I ran Edinburgh pretty hard, after not very much training last year and doubt I could have ran another in 5 weeks (not without a LOT of physio, which I can't afford).
If I train well enough & take it easy in Paris am I likely to be OK? Are entries transferrable if not?
I fancy trying to get a time for Boston
