Nutrition – Caffeine
What do you know about Caffeine?

We all know that coffee wakes you up in the morning and gets us through the afternoon slump. Have you ever noticed feeling an extra boost during a morning workout after drinking a cup of Joe? Caffeine is considered a stimulant and there is research that caffeine improves athletic performance in some sports, especially endurance activities. It seems simple. Just grab a coffee before your race and you have a PR, right? Not exactly. The dosage is important and if you are already an avid coffee drinker the caffeine may not have the same effect. In addition, the exact dose depends on body size, age, gender, and level of tolerance. If you are someone who has the mentality that if a little is good than more must be better, beware. Too much caffeine can actually hinder performance. You might be wondering how much caffeine and when?
Scientists are still trying to figure out the exact mechanism for how caffeine boosts athletic performance. Caffeine works at the central nervous system with the release of epinephrine, which stimulates the release of free-fatty acids and muscle triglycerides used by muscle for energy, sparing the use of glycogen. This could possibly be the reason for why many athletes feel that caffeine allows them to exercise for longer periods of time at higher intensities. It is easy to overdo the caffeine…read more.

Epic Trail Spotlight – The Colorado Trail
Options:
Epic – This trail can be run in one push. Mere mortals can run it in 2 weeks, super human athletes can aim for under 10 hours.
Endurance – If you only have time for a section of the CT, consider the 35 miles between Leadville’s Turquoise Lake and Twin Lakes. This is sections 10 and 11 of the CT.
Bonus – The whole CT can be done on mountain bike with some mandatory bypasses.
Location:
The eastern terminus starts at Waterton Canyon just southwest of Denver.
The western terminus ends in Durang. CO.
Logistics:
Most through travellers travel from east to west. You can park a car in Durango and take a bus to Denver.
Length:
483 miles from end to end
Weather:
The general rule is that the CT is snow free by July 1st and the CT “season” is primarily July and August. Weather conditions in Colorado change quickly. You can encounter any kind of weather any time of the year, so please plan ahead and dress appropriate for the weather conditions. Much of the CT is at high elevations, the sun is intense (wear sunscreen) but it is possible to encounter snow or thunderstorms at any time.
Terrain:
Because of the elevation and the often steep terrain, the entire trail is not suitable for the beginner hiker.
Side Notes:
Do your best to prevent altitude sickness. If possible, give yourself a couple of days in the Denver or Durango areas to allow your body to adjust before you begin your adventure. A slow, gradual ascent can also help; generally, east-to-west on the CT allows for a steady acclimation.
Training – INCREASING MUSCLE MASS FOR THE ENDURANCE ATHLETE
Increasing muscle mass is a common goal for many endurance athletes. As it should be, an increase in muscle mass will bring an increase in strength and performance. Strength is what separates those at the top of the hill with those at the bottom. Although genetics plays a large role in how much muscle mass an athlete can acquire, proper workouts and nutrition will support or negate an athlete’s efforts to increase their muscle mass and therefore strength. Today we’ll discuss the important of supporting strength training workouts with proper protein ingestion, timing and type.
RDA’s of PROTEIN:
Recommended Dietary Allowances for endurance and strength athletes ranges from 1.2 to 1.7 gram of protein/kg of body weight/day. For example a 120lb women needs between 65-93gr/PRO/daily, and a 160lb male requires 87-124gr/PRO/daily. This is a significant amount of protein that needs to be ingested daily. The timing and type of protein consumption is yet another matter in this equation.
QUANTITY and TIMING:
Recent research supports the consumption of 20gr of whey protein every 2-3 hours over a 12hr period. Studies found this timing and type of Protein feeding to significantly stimulated protein syntheses throughout the day compared with other feeding regiments. Studies were conducted with casein, soy and whey protein ingested varying amounts and timing. Muscle biopsies were taken 5 times during a 12-hour period. The researchers concluded that “the effect of modulating the distribution of protein intake…has potential to maximize outcome…. for attaining peak muscle mass” (Areta et el). Although the research suggested that whey protein is the best source for increasing muscle mass, all protein types will produce an increase and preservation of muscle mass. Research often leaves out the daily limiters of real life athletes. Whey protein is the fastest digestible type of protein, making it a good choice for post workout consumption. But eliminating other protein sources from ones daily diet can be impractical and unhealthy.
PRACTICAL APPLICATION:
If you’re like most endurance athletes the idea of eating every 2-3 hours is already a well practiced ritual. You’ll just need to rethink a few of your food choices. Protein sources with whey include but are not limited to: Milk, Cheeses, Eggs, and Greek Yogurt. My go to post workout food choice is a big bowl with fresh fruit, blueberries or seasonal, ½ cup of Greek yogurt (11gr/PRO), and 1 cup of High Protein Kashi Cereal (9gr/PRO). So eat up and support your hard earned muscles!
