Gu Roctane Energy Gel Review

How I rated the gels:

I broke down each brand's product line into organic vs non-organic and then any additional differences such as the type of energy gel. Instead of writing a review on every single flavor, I commented on the flavor within each category. Since there are so many different flavors of gels I didn't rate on the specific flavor, instead, I noted my own comments on each flavor tested. I tried not to let the actual flavor interfere with the overall taste. If I did have a biased against a flavor I noted this in the comments next to the product. To rate the energy gels I used four factors on a scale of 1 to 10. 1 being the lowest score and 10 being the highest score:

1. Energy Availability

This is how quickly the energy became available after taking the gel.

2. Energy Duration

The most important factor was judged on how much energy was given from the gel. A scientific lab experiment was not done on the exact energy outputs of each gel. Instead, I ran a total of 3 miles (30 minutes - because I pace easily at 10 minutes/mile) during each energy gel test. I ran each morning at the same time on an empty stomach to baseline the results as best as I could. I took one gel 15 minutes before each 30-minute running session. Note: energy gels are meant to be taken when your run duration lasts 90 minutes or longer. I'm not advising you to take a gel for a 30-minute run. These test runs were done as close to a baseline as possible to get a decent set of comparable results. I will be updating this post at a later date that rates each gel for longer distance runs with multiple gel packs consumed.

3. Availability

Is the product available in physical stores and in big online stores?

4. Natural ingredients

How many natural ingredients does the product have?

Special note – Rocatane gels are NOT needed for half marathons.

These gels are used primarily for ultra races and ironmans.

Energy availability

The energy was available after waiting 15 minutes.

Energy duration (30-minute test)

This gel hit the mark with keeping my energy level up for the 30-minute test. I was able to mentally focus without any cloudiness. The energy sustained my pace for 30 minutes. No dragging whatsoever.

Store Availability

These gels are the most widely available in the United States. They are also almost always at all running stores and sometimes found in big chain grocery stores. They are abundantly available online through Amazon and other retailers. Don’t forget that half marathons take planning so you’re not caught trying to find your energy gels at a store on race day morning.
