Item # HMN0017


Have you ever started feeling sore immediately following a long ride, or maybe even toward the end of tough effort, before you're even off the bike? If the answer is yes, your long-ride nutrition regimen has a gaping flaw that can be repaired instantly with Hammer's Perpetuem Solids. But before explaining the benefits of Perpetuem Solids you really need to know why you've encountered early exercise-induced muscle fatigue.

Your body in hour three or later of a long, sustained effort is a lot like your laptop computer's OS running 19 programs at once, in the breeze-less, 90-degree-sun, the fan blowing full, and the battery at 12%. The longer you stretch your own "computational" capabilities, the more you're calling upon finite resources. On a ride lasting longer than two hours, refueling with carbs is no longer enough. This is because even the process of converting carbs into fuel scavenges other critical resources, like amino acids. And the conversion of any carbohydrate or other fuel, whether consumed or already in your bloodstream, creates a chain reaction of oxidization, where free-radicals are released, creating harm (and performance limitations) throughout your entire system. And ...complex carbs, soy protein, and amino acids to stave off muscle fatigue... though aminos are also anti-oxidants, your body is calling upon them for energy conversion, limiting their use for fighting off oxidization. The harder you work, the worse the drain on your limited amino supplies and the broader the free-radical release.

Because bringing a turkey on rye in your jersey pocket isn't especially convenient for mid-ride refueling, Hammer makes Perpetuem Solids in tablet form. A caution here: This isn't a sugary Snicker's bar or other highly sweetened gel. Hammer specifically makes the 33-calorie tablets small enough to chew and purposely avoids any refined sugar use, which will incite that awful spike-and-crash cycle that leads to highly uneven performance. That lack of refined sugar does make consuming Perpetuem Solids some level of work, because they're fairly hard and crunchy, so most athletes make sure to consume them one bite at a time, chewing through them when the ride-load is less intense, but at regular enough intervals to stabilize the losses caused by the effort or race.

By the way, instead of using refined sugars for fuel, the complex carbohydrates in Perpetuem Solids come via maltodextrin, which has the advantage of being gluten-free for those with wheat allergies, and it metabolizes more slowly and consistently. Protein is sourced from soy, which is more readily digestible during exercise than the whey you'll find in Hammer's recovery powders, like Hammer Whey. Further, Hammer includes Carnosine, a combination of amino acid and stomach-acid buffer that your body needs to both fight free-radical production and more efficiently process the protein/carbs in Perpetuem Solids tabs.

Hammer Perpetuem Solids are a ready and convenient, critical long-ride food containing complex carbohydrates, soy-derived protein, and amino acids. They are sold in a 90-tablet container and flavors include Caffe Latte (contains caffeine), Orange Vanilla, and Strawberry Vanilla.

What every endurance rider should use

  • Familiarity: I've put it through the wringer

I have used this product since it has come out a couple of years ago, switching from the Perpetuem powder which tended to "sour" on a long hot ride. I have been extremely pleased with the results, it provides steady energy, no stomach problems, and tastes good (I use the caffe Latte)

I tend to cramp about 90 miles into a century, especially in heat, and these have helped alleviate that. On a long ride, I fuel with a mixture of these tabs, gels and plain water in the bottles for best results.
