I am signed up to do a half marathon in 12 days time. The last one I did was 6 months ago but I haven't done any runs longer than 6 miles since. I am currently running 6 miles/10km 3 to 4 times a week but seem to be unable to squeez in the time to do anything more. Do you think it's possible I will manage 13 miles (with grace) in 12 days or am I setting myself up for a fall (and a dismally embarrassing finish)?? What have your training schedules been like???
