Im 72 years old. I train on Zwift nearly daily, amassing 1000+ miles per month. I've ditched the spoon and fork as and energy souce, that's for recovery. I power my rides exclusively with products like Hammer Gel. I can measure more precisley entake and know exactly when to grab my refill pouch. With Hammer Gel I NEVER hit the low-energy wall. I have learned to refuel before the lag and even if I hit a dip, I take a sip and ten
minutes later all cylinders firing.
I really like Hammergel I carry a squeezable refillable flask with 5 servings and rarely use more than half even on my longest 3+ hour rides. I find eating solid food on a ride will sometimes upset my stomach but this never does. A quick hit every hour or so with a swig of water keeps my energy level steady and prevents me from bonking. Highly recommended.
I use this when I need a quick energy boost before rides or runs. The espresso flavor is tasty, not overly sweet, and seems less viscous than some other gels (thus, easier to take without water). The espresso flavor has 50mg of caffeine, which is just enough caffeine when I don't have time to slug a real pre-workout espresso. Hammer's big bottles are cheaper on a per serving basis than individual sachets, and let you take as much or little as you want without the fuss and litter of individual sachets.
A good deal if you grab some hammer gel flasks, and can handle refilling your own flasks. There are rumors that if you are on the trails in forest park, you might see a wild eyed man with very short hair downing a whole bottle of the espresso flavor.
This gel sits well on my gut during hard workouts and tastes delicious. Espresso and Chocolate Hazelnut are my favorite flavors (pro tip: drizzle this flavors on pancakes and waffles if you're out of maple syrup). The big bottle is more economical than single serving gels on a cost per serving basis.
This product works well. You will not feel a rush of energy, but rather a steady, even level of energy.
In addition, Hammer gel flavors, at least the ones I've tried,orange,tropical and raspberry are not terribly sweet. Lastly, even though this is not important to some, it may be to others, these are vegan products.
I use gels for nutrition on longer rides in place of more solids as I have digesting the solids. The Hammer product provides the calories and electrolytes that I need. Buying in bulk and using the hammer reusable bottle saves a great deal of money and helps protect the environment by eliminating the foil packet trash.
The downsides to the combo 1) the bottle has a protective cap and a VERY tight pop top makoing it difficult to use while in motion and 2) the last few servings are a little more difficult to get out of the reuseable bottle. This is overcome by adding a bit of drink from your water bottle prior to starting out making more of a liquidized gel.
I've been using Hammer Nutrition Gel for an energy source for all my rides from a quick hill training ride to 24-hour rides. I use it along with Hammer's Perpetuem and electrolytes in my water as a constant source of energy throughout the ride. It's easy to digest this way. I don't like having to swallow the gel straight and then wash it down, but this approach provides the benefit without the gag. And the variety of flavors keeps things from getting boring.
I bought the "nocciola" flavor, which is great if you like Nutella. It doesn't taste overly sweet, and sits well on my stomach. My wife likes it, too--amazing, given that she can't handle any food or drink before long runs. The large bottle is more economical and environmentally friendly than single-serve packets. Opened bottles don't need refrigeration if you consume all the gel within two months.
I've been using hammer gel for many years. Moreso when I was younger and riding 60* miles at a pop. In summation this is great for a boost on a longer ride to prevent bonking. Now my rides are only 1.5 hours and this is all I have before the ride. I have always used the flavors containing caffeine. Hammer gel has quality ingredients without surplus sugar.
