Has anybody used Run Gum yet? If so, what do you think? I got some samples at the beer mile and I would say there's a couple times where I thought it made a difference. Perked me up a little. Sometimes not so much. I'm not a big responder to caffeine in general though.
Personally I think that "Run Gum" is just some scam made up by Brooks. They make this "performance enhancing gum", slap Nick Symmonds face on the brand, advertise it to all the hobby joggers, and let the placebo effect do the rest. Also, consuming caffeine during every run seems like it would take a pretty bad toll on you, that can't be healthy. If I were to use it (and this is super hypothetical, this gum is manufactured for suckers) I would only use it for races, contrary to Nick Symmonds who claims to use it on every run via his Run Gum Instagram account.
