Joe, way to go - that is incredible!! I've had my share of naysayers also, and yes, that turned into motivation for me also. What did you eat during your marathon? And how much did you need to eat during it? I have gotten through my long runs with enough fuel and tolerable stomach reactions but I can't say I've found anything that has worked well yet. Maybe it doesn't exist but I'd love any suggestions you have!
Thanks for the encouragement and inspiration!!
