Many endurance sports nutritionists claim that runners should spare their limited store of carbohydrate by trying to rely on fat for as long as possible, and possibly by becoming “fat adapted.” However, marathon runners can actually run faster by relying on carbohydrate for as long as possible in the race. As was first discovered more …
Ever been told that running in the heat is like running at altitude? Haha. It’s not. The reason why you run slower at altitude is because of less oxygen delivery to skeletal muscles because of the lower partial pressure of oxygen in the air. The reason why you run slower in the heat is because …
I once dated a girl who had a thing for my calf muscles. Seriously. Calf muscles. She may have been on to something. Did you know that the energy cost of calf muscle contraction in highly trained runners is nearly 25% of the total metabolic cost of running? In recreational runners, it’s 40%. That’s a …

I went to Tambach track overlooking the Great Rift Valley in Kenya to do VO₂max intervals at 6,400 feet. Since the Kenyan athletes don’t typically do intervals on Mondays, it was nice to have the track all to myself. The defining characteristic of altitude is a lower barometric pressure, which keeps decreasing the higher up …
Speed-type distance runners, who have a generous amount of fast-twitch A muscle fibers, may benefit more from a high volume of interval training to improve endurance compared to endurance-type runners. Running many weekly miles at a low intensity doesn’t do as much for speed-type runners. Endurance-type distance runners, on the other hand, get a lot …
Today marks 9 weeks of living in Kenya. Here’s what I know for sure: 1. When you hang dry cotton T-shirts and underwear after washing them, they dry stiff, as if they have been starched. I miss fabric softener. 2. There is a lack of scientific and individualized training in Kenya, which makes the …

Running technique has a lot to do with the angles at which the runner’s legs and feet strike and push off the ground. When your foot lands on and pushes off the ground, it applies a force to the ground. As Isaac Newton taught you in high school physics class, for every action there is …
If you run with a dog or watch a horse race, you’ll notice that animals don’t stretch before or after they run. Most runners think or are told they should stretch before or after running to prevent injuries, improve performance, and alleviate soreness after a workout. Humans are animals, just like dogs and horses. Our …
Have you heard that 80% of your running should be easy and 20% should be hard? Don’t listen to that. The often quoted 80/20% intensity distribution is based on descriptive research on elite athletes who train 10-14 times (10-25 hours) per week. Elite runners do a lot of high-intensity training, but they do such a …
