ALso known as running in the summer on the occasional black top. Soo, I've finally made some consistant progress in that I ran my first 5.2 miles last week totally barefoot on varied surfaces. It went fine; I just need to smooth out the form and get into a habitual rhythm which will come with practice. This will be my first summer and today my first day of running in 80+ degree, full sun, weather. Do any of you seasoned BFRers run on the black top, even for a short distance? That stuff is bloody hot and it certainly makes you pick up the tempo like one of those damn desert lizards running on sand. The run isn't totally on black top, just a short part of it. I can understand the foot adapting to cold and other rough conditions but that amount of heat is rough. Then again I couldn't imagine my foot being able to handle miles of gravel but it does.
