What is it?
A gel or a spray that is applied to the skin and creates a cooling or numbing sensation. It provides temporary relief from aches and pains. It can be used before, during, or after a run. It’s usually applied to the legs. Some marathons provide these products for runners to apply during the race.
My Experiment
I had a 20 mile run scheduled so I figured this would be a good time to try it. At mile 15 my legs were starting to ache. I applied the gel and it immediately created a nice cooling and numbing feeling, just like it’s supposed to. It relieved some of the pain. I reapplied at mile 17 and 19. It didn’t magically make the run feel easy, but it was nice to have.
Is it worth using?
It is worth using on difficult runs. I would compare it to a cough drop - it doesn’t cure the sore throat but it provides temporary relief. Once you start getting into the later stages of a hard run it’s nice to have any type of boost for your body and mind. I started using it regularly on my long runs, but it isn’t a big problem if I forget it. I don’t think I would use it before or after a run, it doesn’t seem necessary.
Some More Info
What are the cons? You have to carry it with you. I put it in a smaller container so it wasn’t an issue, but I know some runners don’t like to carry anything in their pockets. Also, you have to stop and apply it, which can take a little bit of time.
Is it hard to apply? No, I think the gel is the quickest and easiest to apply. It takes about 10 to 15 seconds to apply to one leg.
How long does it last? The gel I use lasts for about 15 minutes. After that the effects start fading away and you can reapply. It seems to be more effective and last longer in colder weather.
Is it sticky? No.
Does it make you run faster? I think It made me run slightly faster. If you’re feeling a bit less pain you are more likely to run faster.
How much do you have to use? 1 ounce will easily cover both legs.
Disclaimer: It is NOT a substitute for proper fueling, stretching, and strength training. I think that proper fueling (eating) is the most effective action to take during a run. These gels are NOT an effective way to treat an injury.
