Wintertime Intensity

How about a little anaerobic work to go with your sweet spot base training? At FasCat in the wintertime we like to caress and nurture our athlete’s anaerobic system. One training myth we’d like to dispel is to only do base training for 2-3 months. Why not do both simultaneously, in the right amounts. We’ve long been fans of fast fun wintertime group rides for the short 10 – 20 second forays above threshold we see in athlete’s power data. While not a ton of time is spent above threshold there is value and benefit to including anaerobic work to your base training. After all, isn’t this how the sport of cyclocross was invented? 54547Wintertime Intensity Training Plan. 1 hour workouts Zwift Compatible.

This year a number of athletes are missing group rides not only for the social aspect but also for the training. And not only the base miles training and TSS but the anaerobic component that makes these group rides so beneficial. Doing a group ride on Zwift (not a race) over variable terrain with mixed high and low power output is OK but not quite the same as these 5 workouts we are presenting below.

First, what is ‘Wintertime Intensity’? Wintertime Intensity is 2 – 4 cumulative minutes of zone 6 work per hour. Two to four minutes is not a lot considering a one hour criterium or cyclocross race has more than half or 30 minutes spent in one’s zone 6. Wintertime Intensity as you would guess is prescribed in the second half to final third of one’s aerobic endurance phase or CTL build. As in our sweet spot part 3 plan or our new wintertime intensity plan.

These variable power wintertime intervals mimic the power demands* of road, mountain bike, gravel, fondo, cyclocross and even punchy time trials. In this training tip, we’ll describe the how, what, where, and why of wintertime intervals and give you five progressive workout examples plus a link to our WinterTime Intensity Training Plan that includes these 5 workouts** in an easy to follow, simple and affordable training solution.

The Wintertime Intervals are what we call variable power workouts and they have 5 main benefits:

1. Specificity of real world conditions
2. Help the time pass quicker during indoor training sessions!
3. Concise short high quality 1 hour workouts (designed for indoors and ERG mode) but just as easily performed outside with longer zone 2 warm up and cool downs.
4. Nurtures your Anaerobic System
5. Provides an introductory amount of intensity to one’s base training before the high intensity interval training phase

Wintertime intervals are structured over under or criss cross style workouts with short 10 – 20 second efforts at the beginning and/or the end of the interval. For example 10 seconds @ 150% on FTP followed by 2 minutes and 40 seconds at Sweet Spot wattages and/or heart rates followed by 10 more seconds @ 150-200% of one’s FTP before a 1:1 work to rest ratio 3 minute recovery. Then repeat.

That’s a 3 minute variable power sweet spot effort with 20 seconds total (10 second before and 10 second afters on zone 6 work of zone 6 work. One can do 6 of these in a one hour workout for 18 minutes of ‘wintertime intensity’ split 88 % sweet spot and 12 % anaerobic zone 6. Or 16 minutes of sweet spot work and 2 minutes of anaerobic work. That’s a perfect ratio for your wintertime base training Dec-Jan-Feb. Now the progression lies in spending more time in sweet spot and more time in zone 6 in the context of a one hour workout.

To get started with your wintertime intensity interval training we have the FasCat #1 Sweet Spot Cheetah Pounce” 4 x 6 minutes. We like to have a little fun with sports psychology and animal imagery in these workouts. And of course we are talking about the world’s fastest land mammal, the cheetah.

Carefully sweet spot stalk your prey (your prey being your training goals) at sweet spot wattages and/or heart rates for 5 minutes and 40 seconds and the “pounce!” on them for the final 20 seconds at a 115 – 150% FTP Zone 6+ effort. Pounce out of the saddle as if you were going for the win and and uphill sprint. Really give’er here because you have a 3 minute recovery interval after. Take a 2:1 work to rest ratio 2 minutes recovery and repeat 3 more times. If all goes well and you FtFP your power and heart rate data will look like this:
