Base Training For 100km Trail Race

How do we get maximum benefit from base training for 100km? What is the Base of training?

This is the most important phase of training.

Here we complement the post Training For 100km Trail Race: 16 Week Overview by diving into the details of the 8 week base phase.

What is Base Training?

The point of Base training is to develop a well balanced athlete capable of optimally responding to the stress of competition specific training.

All peak training is dependant on the quality of base training.

Base training is where the majority of fitness gains are made. These gains are dependant on a consistent and progressive workload. This training may not be the coolest type of running. Without it we gives ourselves a higher chance of failure.

Consistency and Progression

If I could pick one element to focus on it would be maintaining consistency.

Doing what it takes to keep up a solid work load each week is paramount. I will back anyone who can put in moderate running every week over someone with a few big sessions but gaps in between.

The biggest killer to consistency is intensity. Beware pushing the pace. Err on the side of too easy and cover the distance. Allow your body to back up training days. Pushing on your limits forces more down time.

Progression in training should come from gradually extending out the running volume over the weeks. Nothing crazy, but keep running further.

Over time your normal running pace is likely to get faster for the same effort level. Let it do so, but make sure it is the same effort level. We shouldn’t be forcing the speed higher.

What About Speed In Base Training?

Speed is an extra in a 100km race.

Too much emphasis on speed work or high intensity running will take away from the race. Especially during base training for a 100km trail race.

We still need condition the fast twitch muscle fibres and connective tissues.

A good approach is incorporating a few strides in 2 easy runs a week. Run for about 10 seconds building to a moderate and comfortable sprint 2 to 6 times.

Strength training should form part of base training.

Lifting some heavy weights will stimulate the tendons and fast twitch muscles. While giving the body reprieve from the high impact of high intensity running.

Keep it to 2-3 sets of 4-12 repetitions. Avoid going for lots of repetitions (20+). Aim to address the main muscle groups and any area that you are lacking in.

Strength training doesn’t have to be complicated. I have more detail in Basic Strength Training For Runnering.

Base Training For 100km Example

The plan versus reality doesn’t always match.

For me the structure of a base training week would look like this:

MondayTuesdayWednesdayThursdayFridaySaturdaySunday
Long Run 30-42kmEasy 40-90minTerrain Run 3 hoursEasy 40-90minTempo Run 14kmEasy 40-90minEasy 40-90min

If you are using this as an example to follow you may want to change around the days. For me each week will vary because I do rotating shift work and don’t follow a normal weekly pattern.

I try to avoid scheduling the bigger runs on weekends as my kids have their sport on these days. There is an element of creativity that goes into finding ways to fit it all in. That is worth a post all on it’s own.

See you in the next post as I break apart more of my training.
