Training for an ultramarathon requires a variety of
different types of training runs and races to prepare for 100 miles. But first, what is an ultramarathon? An ultra is any race longer than a
standard marathon (26.2 miles) and typically is run on a network of trails
through the woods, mountains, and valleys.
The most notable race being the Western States 100, the first 100-mile race held in the Sierra Nevada Mountains. Originally a horse race, riders would ride
from Squaw Valley to Auburn in 24 hours, but in 1974, Gordy Ainsleigh’s horse
went lame, so he decided to run the rest of the race on foot. In the following years, the sport took shape
and now there are 100-mile races all over the country.
So how do you train for something like this? There are a lot of factors to take into
consideration. What is the race terrain
like? How much is the gain in elevation
over the course? What elevation above
sea level is the course? How much will
you have to run or hike? If you are
running a marathon through the mountains with a ton of climbing, you will not
want to do all your training on a flat road.
Your training should be race specific.
The first thing, and maybe the most important, is having a strong base. ~6 weeks of consistent running before rigorous
training will help avoid common running injuries (planter fasciitis,
tendonitis, strained muscles). If you
start off too hard, they can sneak up on you and create big problems in your
training down the road. Some injuries
may be inevitable, but starting steady will give you a strong foundation to
build off.
Once you have a strong base, there are a multitude of
training runs you can do, which I will talk more in depth about in future
posts. But what is important overall is
that your training should address the rigor of the course to make you best
prepared come race day. For example, the
first race I have coming up in training for Leadville is a 33K (20.5 miles) on
February 16 in Moab, Utah. Since it
would be difficult for me to go to Moab to train every day, I can study the
course map and elevation profile to cater my training towards this race.
Although this
elevation profile is simplified, there appear to be three peaks, so I try to
break down the course into each segment to determine how rigorous the climbs
and descents will be.
Climb 1: +400
ft/1.5 mi
Descent 1: -400
ft/1.5 mi
Climb 2: +800
ft/4 mi
Descent 2: -600
ft/4 mi
Climb 3: +100
ft/1 mi
Descent 3: -900
ft/6 mi
Net Elevation
Gain = 3,326 ft
Note: The
course is 20.5 miles long, but the profile only shows up to mile 18.
The net elevation gain is much more than the climbs I calculated, so this mean there must be a lot of up and down segments throughout the entire course. Once I break
down each climb, I can look at trails that I typically run on to gauge the
difficulty of each pitch and how fast I should be able to run each
segment. Studying the course before you
get to the race will be incredibly advantageous for any runner because you will
have catered your training towards that race to be mentally and physically
prepared for each segment. Also to note is the elevation above sea level, as anyone who has traveled to Colorado can attest, breathing becomes more difficult. Since I live around 5,200 feet in Boulder, I will not have to do much elevation training for this race, but as I mentioned before, Leadville will peak at 12,600 feet, so training at that elevation will be important later on.
