At first blush, this stuff works. I've been rocking Topical EDGE on my Saturday Bubba rides. I'm out of shape. Too much work and not enough play put me in a bad spot, creating better circumstances to test this stuff.\nBubba rides are 60-80 miles with 2-3 climbs, so not easy rides in quality or quantity. Usually, I can hang with these guys early but after every pit stop, the fatigue and stiffness steadily set in as we roll away for the next segment. What I noticed with Topical EDGE is the lack of built up "junk" in my legs that my lack of fitness couldn't clear. It allowed me to stay with the fast guys longer and deeper into the ride. I love it.
