This is a pet subject for me since I'm currently training to do my first half-marathon. I found this excellent and insightful article on the Runner's World website. I only wish TBL offered this much detail. I'm not posting the article here as it's quite lengthy, but please do give it a read - there is a whole lot of advice regarding marathon training and nutrition, and it focuses on the Season 10 finalists (Ada, Patrick, Frado, and Elizabeth). It's really inspiring...I had been waffling on whether or not to stick to a 10K this spring or go for the half-marathon, and after reading this I was sold.
