Atomic Balm and Red Hot. I just bought this stuff yesterday. 40 miles on the road bike last night with the Atomic Balm on and no knee warmers and my legs were toasty. By the time I got home I was exhaling condensation, it was cold, like 44 degrees cold and my legs were warm. I tried the Red Hot in just a small spot and it might be TOO HOT. When I got in the shower after the ride it was still working, kinda like sunburn, and it was still working when I went to bed! Good stuff, so if you smell some Ben Gay sort of smell on the start line of the next cross race, it's me.
