Wanted to share with the group that I ran my first marathon in Barcelona while on vacation with my family. My 4:49 time is a bit shy of qualifying for Boston but I don't mind.
Hydration during the run went well. I wore an S-Lab Skin 5 Salmon vest (expensive but unparalleled comfort) with 5L of 80% coconut water and 20% water. This lasted me until mile 13 when I stopped at a fuel station to reload the bladder with powerade and water.
As for eating, I had a small amount of toast with pate along with a Saltstick rehydration pill prior to the start. I took another pill at mile 13 and a third at mile 20. During the run I had 4 GU gel packets and 4 Nutri grain bars. I had kept this exact regiment during my training runs so I knew it worked for me.
It's been about 2 years since my takedown and my health has been great. I have about 3 to 4 bowel movements a day rarely with urgency. Even with exercise I rarely feel dehydrated.
Not one to normally post about personal accomplishments but I hope this is encouraging.
Best of luck to others with exercise goals. Big or small, you can do it!
Cheers,
Paul
