I'll second the suggestion to check out the exercise forums. I know there are some runners hanging out there and they would probably have advice cfor you re: nutrition and endurance training. Link: http://forum.lowcarber.org/forumdis...?s=&forumid=112

Also, I know ysabella (another forum person) is training for a Danskin Triathlon later this summer. You might want to pop over to her journal at http://forum.lowcarber.org/showthre...15&pagenumber=1

Good luck!
