For those of you, like myself, who are potentially facing triple digit temperatures to match a triple digit race distance, here are some things to consider to keep your ‘A’ goals from evaporating.

If you spend any amount of time talking about ultrarunning nutrition, you are almost certain to hear the term “fat adapted.” The general idea is that a “fat adapted” athlete will be very efficient at burning fat and thus have an immense supply of stored fuel, eliminating the need to ingest large quantities of carbs.

Barely past the halfway point of Run Rabbit Run 100 last September, my legs and feet rebelled. Stiff muscles, achy joints and soles so tender that I winced with each step conspired to abort yet another attempt to run. Dejectedly hiking in the fading light of dusk on a gentle stretch of trail above Steamboat Springs, I said to my pacer, Jacob Kaplan-Moss, “Sorry, this is all I can manage right now.”

Man came out of darkness and into the light, and that was my experience during the 2003 Angeles Crest 100.…

When I first found out I was pregnant, I googled “running while pregnant” and was disappointed in the lack of information out there. There was information about Olympic athletes and information for recreational runners, but not much for someone who fell in between these two categories.

There are many aspects of the ultrarunning community that I love, and one of the most important is the fact that at 99% of races 99% of the folks out there helping the runners are volunteers. It’s easy to take this for granted and just assume that races are volunteer run. But have you considered how a race might differ in atmosphere if the folks handing you water or issuing your bib number were paid employees?

My first experience with significant overtraining from running occurred during my two years of collegiate running for CU-Boulder. I was a decent, All-State high school runner in Colorado’s second largest school class, but my talent and experience were years behind many of my teammates like Dathan Ritzenhein, Jorge and Eduardo Torres, and Steve Slattery. Totally pumped by the simple fact that I had made the team in the annual tryout for a few walk-ons, I dove enthusiastically into my training.

At the end of the year, most of us back off training and allow for a little downtime and reflection, plus, family commitments are especially time consuming (and fun) during the holidays. What should you consider when thinking ahead to next year to allow yourself to keep progressing and improving your running?

By understanding the physiology behind thermoregulation, we can be better prepared for our summer events. Here’s what you need to know about what causes body heat to increase, heat loss mechanisms, why athletes perform worse in the heat and factors to improve performance in the heat.

There is no question that fatigue is the result of physiological compromises in a host of bodily systems (muscular, nervous, hormonal, skeletal, respiratory, cardiovascular, etc.) during an endurance event. However even more critical to this weakening of the systems is the perception of fatigue being encountered. It is the brain that continuously monitors endurance performance and it this organ that eventually determines how far fatigue will be endured.

Throughout 2016, we have analyzed the fundamentals of efficient running mechanics and how the demands of the ultra distance impact our run. Last month, we discussed arm swing. This month, we address the powertrain – the hips.

No one watches the long-range weather forecast like an ultrarunner. Whether we are planning some long training run or preparing for an event, nothing weighs as heavily on us as the forecast. Of course, it really makes little difference if we are headed to a race. Having invested our children’s inheritance in the entry fee, we’re going to go no matter the weather.

A few years ago, I started pulling a tire back and forth over a local bridge as part of my endurance training, and as you can imagine, it encouraged some interesting remarks from passersby. “I think there’s something chasing you,” to “Let me sit in there,” to “My dog would love you to pull him around,” were the norm.

The inspiration to write this piece comes from a lifetime of loving dogs and living in their love. I have watched throughout my life, some of the happiest moments occur between humans and their wet nosed soil-sniffing companions. I’d argue – that some of the strongest bonds of love found on this planet have been forged between the two and four-legged.

At this time of year, how did you go about planning your races and schedule for the upcoming year? Also, how did you approach these winter months? I’m getting stir crazy and want to be out there, racing long out on the trails, right now. How do you approach and handle this?

The 4th annual SF 100/50 Mile Endurance Runs takes place on March 26th. The course takes a scenic tour of…

The father had always been old school and a bit old-fashioned. He was a man who could easily handle both a stethoscope and a shotgun, his life shaped by time tending patients in emergency rooms in Roseville, California, and in caring for horse riders, and then for runners, on the Western States Trail.

This is the first in a series of articles on what happens to your body during an ultra, focusing on the sparse but growing scientific literature that exists. However, physiology is extremely individual dependent, so please interpret this column with caution, as we are all different.

I circled the high school track, loop after loop, hour after hour, mile after mile. For 100 miles, to be exact. It was July in southern Utah, where summer temperatures feel like you’re standing on the sun. The high was 107 degrees. I tried to think of some profound response when people asked why I was running 100 miles around a track in July. The best I could come up with was “Well, it seemed like a unique challenge. And I had some glazed donuts I needed to burn off.”
