I'm a fairly seasoned half marathon runner and have gone past that a few times, my longest run is just over 18 miles. I'm not sure I want to do a road marathon but I want to do a trail Ultra! Ran with a running buddy today and we've decided to enter day 2 of Race to the Stones and probably Run to the Sea Bournemouth next year. I know I'll need to do a Spring marathon and I'm really excited to have a challenge!
