Sometimes life is pretty cool. A prime example of life being pretty cool occurred recently. I was offered another opportunity to test and review additional flavors of Science in Sport (SIS) isotonic gels. During and since my initial trial and review of SIS gels, they have become my “go to” energy gel for endurance events and long training days so I was super pumped to try more flavors. This time around I received three flavors to try: salted strawberry, apple, and orange (75 mg caffeine). I was especially happy to see the caffeinated orange flavor in this round. I had previously tested the double espresso (150 mg caffeine) flavor which turned out to be one of my favorite flavors. However, the 150 mg of caffeine in every 90 calorie gel was a little too much caffeine for me if that was the only flavor I was using. Having the option to spread out the caffeine intake between gels was a very welcome choice.

During my first trial of SIS gels, I put them to the test at two last person standing events and was absolutely pleased with their taste, how well my body was able to process them, and the energy they provided. For this trial, I put them to the test again and used them as my primary calorie source for a 106 mile FKT attempt on the Batona Trail (22:46:42) in South Jersey. Once again, SIS gels delivered the sustained energy I needed for long strenuous effort. My energy levels never crashed with my steady stream of calories via the SIS gels.

Of the plethora of brands and flavors of gels I’ve tried over the years of running ultras and eating whatever brand of gel happens to be at the aid station, I’ve found that the flavor and consistency of SIS gels work better for me than any of others. Usually after a long ultra my teeth hurt and I am almost sick to my stomach of forcing down overly sweet gels with overpowering flavors. This doesn’t happen to me when I use SIS gels, even after 20-30 some hours of eating them on three occasions. The flavors are not artificial tasting like I find most other gels to be. The lighter consistency makes them easier and faster to consume than your standard syrupy gels which also means you don’t feel like you have to rinse your mouth out after eating them.

So what’s the deal with “isotonic”? Well, it’s the reason why SIS gels aren’t a syrupy gooey mess like the majority of other gels on the market. They are the first of their kind. To explain it in more detail, we have to review a little high school biology terminology:


Hypertonic: If a solution is hypertonic, it has a higher concentration than the fluid in the body. This means that water particles will have to be pulled from the cells into the gut to help it absorb and balance up this concentration. This slows down the availability of the energy from the gel and can bloat your stomach and be very uncomfortable.

Hypotonic: If a solution is hypotonic, it will have a lower concentration than the fluid in the body. This means that it will empty quickly from the stomach, but it will not contain much energy.

Isotonic: To be isotonic a solution must have the same concentration of dissolved particles as the fluid in the cells within the body, typically this means having a tonicity between 280-310 mmol/kg.

So what is the benefit of SIS gels having the same concentration of dissolved particles as the fluid in the cells in your body? 

1. They provide a quicker supply of energy to the working muscles than thicker, more concentrated gels.
2. They’re absorbed without needing additional water.
3. They’re easily digestible and light on the stomach.

If you’ve never tried SIS gels, I highly recommend giving them a shot. If you decide to, be sure to use the discount code “BIBRAVE20GEL” for 20% off (not applicable to already discounted products or special offers.)

Using the California Coast 500 Virtual Challenge as Training for my 106 Mile Batona Trail FKT Attempt

"Disclaimer: I received an entry to the California Coast 500 Virtual Challenge to review as part of being a BibRave Pro. Learn more about becoming a BibRave Pro (ambassador), and check out BibRave.com to review find and write race reviews!"

If you’re a regular reader of my blog, you’ll know that due to COVID-19 I ran my first virtual race this year. If not for COVID causing basically all races to be cancelled, chances are that I would not have dipped my toes into the virtual racing world. But, alas, I am adjusting to a “new normal”, willing or not. And with that adjustment, I just completed another virtual race challenge, the California Coast 500! 

I decided to run the California Coast 500 for a few reasons. One of the major reasons was to stay motivated to run throughout the spring and summer without having any “in real life” races to run or train for. Granted, even without racing I would likely still run just for the fact that I enjoy it for a multitude of reasons that I won’t go into here, but actual in person races definitely give me something extra to be excited for and get me to train harder than if I am just running for the other benefits that running provides me. So I used the California Coast 500 as a means to train for the fall races that I was still hoping would happen. As the COVID situation developed and races further and further into the year continued to cancel, I lost that hope. Rather than being upset at a situation that sucks, but is out of my control I decided to adjust my plans and use the California Coast 500 as training for an FKT attempt that will not be cancelled. 

I decided I would make an attempt at the self-supported Fastest Known Time (FKT) for the out and back Batona trail route. The route is about 106 miles of pretty much flat, nontechnical trail. This would be my first FKT attempt and using a long distance virtual challenge as a training plan was completely new to me as well. Having just finished the 500 mile challenge today and planning to make my FKT attempt in the next 1-3 weeks, I can not say at this time whether this was a good plan or not. It feels like I’ve had good preparation for a long distance run. I’ve put in higher than normal weeks for the last two months, consisting almost exclusively of slower paced longer runs. Even the shorter runs were usually slower than my other short training runs because I treated them as short active recovery days from longer runs during the challenge. I’m hoping all of these higher mileage weeks at a slower pace will pay off during the later stages of my FKT attempt, but only time will tell how well this plan turns out. 

Other than having the California Coast 500 keep me motivated to train for other goals, the event itself had some pretty cool features that I found to be pretty innovative for a virtual challenge. The first being that a one month free trial subscription to PWR Lab was included with the registration. PWR Lab is an online fitness system created for athletes that easily syncs with data from your smartwatch. The PWR Lab software uses analytics to synthesize that data with running science principles to deliver the PWR Lab Training Dashboard. The Dashboard displays key variables and highlights effects of your training on running power, preparedness, and risk of injury. The data from PWR Lab was also used to track all of the runners’ progress during the challenge as well, allowing them to create some pretty cool maps to track progress.

Another unique feature that the California Coast 500 added to make the virtual race experience more engrossing was to create and share California themed playlists. 

An additional feature that kept me involved and looking forward to the weekly emails from the race was the announcement of the weekly challenges, the associated prizes, and last week’s winners. Challenges ranged from running your highest mileage week, logging three runs of five miles or more, or being an early bird or night owl runner logging your miles before or after a set time. Although the coolest and most fun challenge in my opinion was the chase pack challenge. The chase pack challenge pitted three elite ultra runners (Dani Moreno, Mike Wardian, and Tim Tollefson) against the entire California Coast 500 field. Finish in front of them and be entered to win a pretty nice prize package. Get passed by them, and you are entered to win a pair of running shoes (still not bad). Thankfully, I stayed in front of them. We’ll see if it pays off with a prize!

The last aspect I wanted to mention about the California Coast 500 that really stood out to me was the finisher awards. The awards for the California Coast 500 Challenge are designed and crafted by @elevationculture. Not only do they look great, but all products from Elevation Culture are produced sustainably from renewable sources, byproducts are repurposed or recycled, and all shipping materials are biodegradable.

As an inaugural event and only my second virtual race, I am pretty impressed by what Run Local put together for the California Coast 500. When actual in person racing returns, I predict that the majority of the virtual races that have popped up in the last few months will disappear. However, I also believe that a few that were able to create a great vibe and experience for the participants will stick around. And I also believe that the California Coast 500 could be one of those virtual events that is able to continue to exist even as in person races return to being our norm.
