I'd say to go to a running store and get fitted. They can suggest based on your running style what type of shoe would be best. I run in Asics Kayanos, and have for the past couple of years. But I found them based on running store recommendations. HTH! I run in parks that have bathrooms at certain intervals. But I have been known to run to a bush when needed. I do run in compression legs sleeves over 4 miles. And during the race and after as well- helps my legs recover! Not sure they help during the race, but it doesn't seem to hurt, so I wear them. Energy- any run over an hour I bring some type of fuel. Beans or shot blocks usually with water. I carry a water belt for those longer runs. The shot blocks are about 3-4 blocks an hour, the beans for me is about half a bag per hour.
