Some of you who are on Endomondo may have heard of the exploits of Annette Fredskov Jensen.
This 41yr old Danish woman runs a marathon every day (in around 5hrs) !! Her goal is 366 marathon runs in 366 days (from 15th July 2012 to 14th July 2013). She is not a professional athlete and started running only 5 years ago. 3 years ago she was diagnosed with multiple sclerosis (MS), she is now disease free !
Checkout her website (in Danish with one part in English) or her Endomondo workout table

Puts your own aches, pains & running in perspective.
Cheers
