Beast Coast Trail Running by Scott Snell: Putting Science In Sport Isotonic Energy Gels To The Test

It's a good day when you find this on your doorstep!

What the hell does a totally badass wooden sword and an extremely attractive and unique plaque showing a topographic map of a 5k trail loop have to do with Science In Sport (SIS) Gels? For the majority of people, absolutely nothing. But for me, there is a significant connection as those were the winner’s awards for the last two (and only two) “last person standing” format races that I have run. And during those two races I depended heavily on SIS gels as a major constituent of my caloric intake. It may not be a cause and effect relationship, but SIS gels definitely contributed to my performance to earn those two awards.

The four flavors I tried, sorry, giveaway is over :(

Where to begin with SIS Gels? Well, when offered the opportunity to try out a new type of energy gel I was excited. As an ultrarunner, nutrition is a huge and one of the most important parts of my racing. Calorie intake and your stomach’s ability to handle your choice of calories can be the difference between completely killing a race or having your race end with a dreaded DNF (Did Not Finish). I’m basically a scavenger when it comes to gels, more or less just using whatever gels are offered at aid stations when they are offered. Because of this, I’ve never become brand loyal to any one type of gel. Some have stood out as better than others, some worse than others, but none so much so that I said to myself, “That’s my gel” or “I’m never eating one of those again.” With my history of a hunting and gathering gel practice, I felt blessed to be able to consistently use one brand of gel for the bulk of my training leading up to and during both Run Ragged and Last Idiot Standing (LIS) - Summer Edition.

At the finish of LIS!

For both races I brought four flavors of SIS gels: lemon & mint, salted strawberry, apple, and double espresso (150 mg caffeine). I wanted to have some variety of flavors for these races as I planned on eating 1-2 gels per hour and I did not want to get to the point where I was sick of the taste of a single gel flavor and I had to force myself to eat it. Thankfully, that never happened with the choice of flavors I had for the 32 and 14 hours that the two races lasted respectively. And for the most part, I totally avoided any total and complete bonks. I was starting to bonk pretty hard around the 25th hour of Run Ragged, but then I downed two apple SIS gels and was feeling better within about an hour. I believe that bonk was basically due to me not keeping up on my calorie intake. I had forgotten to eat a gel at several aid station stops and I had not eaten anything else to get any other replacement calories. I didn’t recognize it until the calorie deficit had already built up, but after the SIS gels and some bananas I returned to the best case scenario for someone who has not slept and has been running for over 25 hours.

Of all the gels I’ve tried over the years, SIS gels are the most palatable. Most of the time after a long ultra I am almost sick to my stomach of forcing down gels. This didn’t happen even after 32 hours of eating them at Run Ragged. The flavors are not overly sweet or artificial tasting as I find most other gels to be. Additionally, the consistency is thinner than most other gels I’ve used. The lighter consistency makes them easier and faster to consume and negates the need to immediately wash them down. After hours of eating other brands thicker, almost syrupy, gels during ultras I will begin swigging water or whatever electrolyte drink I have in my bottle and swishing it around in a futile effort to rinse the taste out of my mouth and the sticky coating off of my teeth. With SIS gels I never felt the need to do this. The reason being that SIS gels are designed to be an isotonic formula, or the same concentration as in the body. The isotonic formula allows the SIS gels to be processed more efficiently by the stomach without additional fluids to dilute them. This in turn allows the stomach to process the gel more quickly and get the calories on their way to becoming energy for your muscles to burn.

Packing for a last person standing race, one of the toughest things other than actually running it!

In addition to the better taste and consistency of SIS gels, the boost from the 150 mg of caffeine in the double espresso gels was also a huge help to me in reaching my goals at both races as both races each went from at least dusk to dawn and then some. I became pretty groggy at a few points during some of those early morning hours while I was anxiously waiting for the first signs of the sunrise to show. The kick from those double espresso gels helped me to get out of my chair and continue when a nap sounded pretty nice.

If you’re like me and you have never fallen in love with any one brand of gel, I highly recommend giving Science In Sport gels a try. I can’t and SIS can’t guarantee that you will win every last person standing event you enter if you use SIS gels, but that’s what they’ve done for me so far!
