In order to fuel up during the marathon, I tried a new hydration system from Salomon, the Sense Hydro S-Lab Handheld Hydration Set (pictured above). Each bottle holds 8 ounces, and I filled them with 150 g of maltodextrin (600 calories) in 16 ounces of water. The bottles are held in your hand by the little glove and are very convenient. I drank every 3 miles and finished each bottles in 9 miles. One of the very nice things about these bottles is that they are very light and collapsible. After I finished each bottle I took it out of the glove and just stuck it in my pocket and forgot it was there. I'm not sure I would use them in an ultra given their small size (and I think they would be a bit of a pain to re-fill during a race), but for shorter races they are excellent.
