I recently started structured training, adhering to the fundamentals of building up my aerobic base. Like many endurance athletes, I have probably been training the wrong way for decades, and incorporating too much high intensity training without any coaching or guidance. So as I journey into this new world of Zone 1-2 training to improve my AeT/AnT ratio, I have a question about mid-season racing.

Like many of us, I have 1-2 races which I would like to to do well in later on this summer (ie, 20 mile mountain race with about 6500 vert gain). However, there are a few other shorter/faster races which I would like to do as well (All similar mountain races with considerable vertical gain/loss). Before starting this program and being ingrained in my misinformed notion that training fast makes you race fast, I was planning on these races as part of my intensity training…plus they are really fun.

So the question is, will these “training” races hinder the overall goal ( assuming plenty of time of rest before the main event)? Will they help? Can/should I “race” these which would probably push me into Zone 3 for 2 hours (more or less)? Should I stay in Zone 2 ( which would result in much slower times as previous years).

Thanks, and I really enjoyed the new book. Fantastic job.

You can definitely use races as training, but they can cost you fitness if they dominate your training. That’s why most athletes lose fitness as a race season progresses.

The trick is to keep your low and high intensity within proper proportions. If your goal event is ~2 hours, then I would keep actual minutes of high intensity to about 5% of total training time. (So a ~30′ race during training should be supported by ~10 hours of base training within the same week.)

For shorter goal events (~30′), then you can probably get away with minutes of intensity representing ~10% of total training time.

You may hear people talk about an 80/20 ratio for low/high intensity proportions, but that break down comes from a “session goal approach” where an entire workout is labeled as high or low without regard to its contents.

Thanks Scott,

I have one follow-up question regarding racing/effort/HR. I’ll use an upcoming “training race” as an example. It is about 16 miles total, uphill a continuous 4500 vert, then back down. The downhill route is about 3 miles longer than the uphill.

The uphill is very steep and slow, and much of it is power-hiking. HR will certainly be in Zone 3 and approaching AnT at race pace.

But that is only half the race. Downhill will be very fast (for me)… around 6:15 min/miles. The effort will be quite significant, the legs will be feeling fatigued, but the HR will likely be in Zone 2 for much of that time.

My question is regarding the hard downhill effort. What type of training effect (both cardiovascular and muscular) does one get with a long, continuous, hard, fast, race-paced, and relatively exhausting effort with a relatively low HR that one is affording when running downhill?

Thanks!

Heart rate isn’t a good measure of intensity for downhill running. Even if your heart rate drops, the eccentric load on your legs will be significant, especially at race pace. I suspect it’ll be at least “zone 3”, although at a muscular level rather than cardiovascular.
