New review of the Hoka One One "Huaka"

Here is my review of the new Hoka Huaka; it’s got the thick sole, but little cushioning. Doh! http://fellrnr.com/wiki/Hoka_Huaka

Magnesium for running and health

Magnesium is a critical nutrient, but the majority of Americans are probably deficient. Insufficient magnesium impacts health in many ways, from poor running performance to diabetes, osteoporosis, and even premature aging. There are also indications it can help with migraines, insomnia, and depression. Supplementation is generally safe, though some forms can cause GI problems. I've rewritten my article, reading 100+ research papers over the last 6 weeks. I aim to cover the benefits of magnesium along with an indication of how strong the evidence is for each benefit. http://fellrnr.com/wiki/Magnesium

New Review - Hoka Clifton

Here is my review of the new Hoka Clifton running shoe, including comparisons with the Hoka Bondi and Conquest, and the Altra Olympus and One2. It's a lot like the Bondi, but much lighter and my favorite in the Hoka range. 

Why run ultramarathons?

I've been asked many times "why run ultras?" and spent many hours thinking about the answer, especially towards the end of long races. There is no good answer, but here are a selection of possibilities http://fellrnr.com/wiki/Why_Run_Ultras

 

When I first started to write about the "why" of ultrarunning, I thought that would be two or three possible answers, but over time the list has grown far longer. I've had lots of input and suggestions from many runners, and I welcome further suggestions.

Running Cadence Update

Cadence (how often your feet land) is one of the most critical aspects of running as it can reduce the likelihood of injuries and improve running economy (how fast you run). I've refreshed my page on running cadence to improve clarity, and I've included some more scientific research I found while looking into running economy. 

The update to running economy is taking much longer than I expected as there is a huge amount of research, some of it conflicting. How shoe weight and ground contact time effects running economy is particularly confusing.

Best Hydration Systems

Here are my recommendations for hydration systems, based on my evaluation for running the Keys 100 and Badwater.  (Remember, drink to thirst as overhydration can be fatal.)
