Infinit Nutrition – Perfect Fuel for the Long Haul

by Rich Rothwell, 2009 Masters 24hr Solo Mountain Bike World Champion

As a 24hr solo mountain bike racer, I need no distractions. My bikes need to work perfectly; dealing with any mechanical issues in the middle of the night and after sixteen hours riding is tough. I also need to be able to focus 100% on the technical aspects of riding. And I need to watch my competition. It’s a lot to think about! On top of this, nutrition has to be spot on. It’s hard to eat when you’ve been pushing yourself hour after hour. It’s even harder to eat when you can barely take a hand of the handlebars as you’re flying through singletrack! If you do get solid food down, it often sits like a dead weight on your stomach. Not nice! And I must admit that in the past I’ve never quite got my nutrition right.

I haven’t been using my Infinit mix for very long but I could tell pretty much right away that it has solved my nutritional issue in one go. Firstly, it’s thirst quenching, and I want to drink it. So my hydration is taken care of. I have exactly the right amount of carbs in the mix so I have not once ran out of energy in a training ride or a race – I have completed eight hour training rides, interspersed with heavy threshold sessions, using nothing but Infinit and felt very strong even in the final hour. The protein content helps with ongoing muscle repair but most revolutionary for me is that I just don’t get hungry or feel the need to eat solid food. There is so much less strain on my stomach and when I finish riding I feel comfortable and ready to eat a good recovery meal. Prep for races and big training rides is also so much simpler. I just fill my hydration pack or some bottles and go. This is also a great help for pit crew and support as they have less to think about. I was skeptical of going fully liquid but after using Infinit for some time now, there is no way I would revert to the inconvenience, discomfort and poor energy levels of solid food for endurance training and riding.

Hydration 101


What is the single biggest issue I see with the age groupers I work with? Let me tell you about an e-mail we received. We received a “complaint” from a customer who said he got dehydrated using his custom INFINIT formulation…

First, we very rarely get complaints about the product (if ever). It just does not happen that often and it gets our attention fast. Normally it is from the customer doing too much, we see that over and over. They are drinking their product and happily munching on gels and blocks and wonder why they feel like they ate a bag of nails after 5 hours. This is consistent with AG’ers, they always try and do too much and it leads to issues. Less is better, simple is best.

Here is the issue. Over the past couple of years I have seen a trend. Athletes have no idea exactly how much they should be drinking in order to stay hydrated. It is a HUGE component of how you will perform. If you lose 2-3% of your body weight in water loss you will lose 5-15% of your watts (power output). For an athlete that weighs 150 pounds, only a few pounds that will make the difference between a solid result and potential disaster.

Salt does not prevent dehydration or cramping. That is the stuff of urban legend. Salt is a transporter of fluids. You need salt, but only enough to move water out of your gut into your system. The movement of water is the key to prevent dehydration and possibly cramping issues. If you are not drinking enough, I don’t care how perfect your formulation is, you might be in for a long day. For most males the target should be around 375 mg of sodium per hour and females around 325 mg. It should be a blend of electrolytes containing sodium, potassium, magnesium and calcium. To reiterate, salt is a transporter. You don’t have to overdue electrolyte intake. You only need enough to move the liquids you are putting into your system.
There are two things that you must have in order to train and race efficiently.
DO A SWEAT RATE TEST! How are you going to know how much you need to be drinking if you don’t have a handle on how much you are sweating? Remember, no product in the world is going to prevent you from dehydrating if you are not drinking enough. Your hydration target will vary somewhat depending on the heat and humidity, but this is a crucial component to race day performance.

• Before your workout empty you bladder, and record your weight
• Record how much you drink during the workout
• After the workout, re-empty your bladder and re-weigh yourself
• Take the weight you lost, ADD the amount you drank, then divide by the number of hours you worked out.

That will give you an hourly hydration target. I would do it a few times to have an average. Your hydration target will need to be adjusted somewhat for heat and humidity. But this is key information for performance.

Calorie and electrolyte intake (in a form that is isotonic). Most athletes perform better by not overdoing calories and salt. Rule of thumb is 2 calories per pound of lean body weight. Obviously some people need more and some people need less. Long distance racers typically need more calories per hour than sprint racers. But these are solid starting points based on working with thousands of athletes.

So there it is. With those these small pieces of information you can have a great race.

• Know how many calories per hour you need
• Know how much you need to be drinking per hour
• Put your nutrition in a form that is isotonic

It does not have to be complicated. Remember simple and repeatable. Follow those simple steps and you will perform the way you want with no nutritional issues.
