I posted this video way back at the start of August last year. It has been my most popular post and I swear that someone looks at it at least once a day. If you haven't seen the whole episode where Barney runs a marathon on How I Met Your Mother you should look it up. It's funny and very identifiable if you've run a full!
Good luck to those of you who are running this weekend! I look forward to reading about your experiences in Vancouver, Eugene and where ever else you may be.
