Even when James Blake retired from the ATP Tour, his cramping issues did not.
Training for the New York City Marathon, Blake stumbled across a solution to his chronic cramping.

Now Blake is advocating for the answer to his aches: He's signed on as an endorser for Cramps Away.
The product is a natural liquid supplement that creators claim you can take prior to a workout to prevent cramps, or more impressively, ingest it when cramps have already hit to halt cramping.
"On average, users feel relief from cramps in less than 60 seconds," the Los Gatos, CA-based brand claims.
Blake, who described himself as "extremely skeptical" before he tried it, has signed on as a Cramps Away "founding member", responsible for outreach efforts to select sports categories.
"As a professional athlete, I figured if the product worked as well as everyone said it does, as fast as it does, I would have heard about it," Blake said. "Then I tried it when I started cramping while training for the 2015 New York City Marathon. Within 30 seconds my cramps were gone. I used it again during the race, and it immediately relieved the cramps in my quads and calves.
"I wish I'd known about this product when I was on the tour. I think it's truly going to revolutionize sports."
So does it really work?
We've not tried it ourselves. If you have let us know your experience.
