Climbing Workouts for Cyclists

Climbing workouts in the form of intervals will help you ride uphill faster for your Strava PR’s, group rides or hilly races. Mountain bikers, Road Racers, Gravel, Fondo’s - any athlete that wants to ride uphill faster will benefit from these 3 climbing workouts. 

What do we mean by climbing workouts?

We are talking about intervals with zone 4 threshold wattages, heart rates and rates of perceived exertion (RPE) for durations between 8 - 30 minutes. Using the 6 zone model in TrainingPeaks, zone 4 is equal to 98-104% of one's "Threshold" or Functional Threshold Power (FTP). If you are going by feel," zone 4 is whatever intensity is 'as hard as one can sustain' for not only the first interval but for all intervals.

Threshold workouts are hard and need to be completed when the body is the most recovered, after a rest day or a couple easy days on the bike following a fatigue dependent training plan design.

Moreover, in order for the intervals to be effective, cyclists should use the following guidelines:

  • Identify your FTP [Functional Threshold Power]
  • Identify what value is 98-104% of FTP**
  • Perform these intervals hard as you can go "Full Gas", Heart Rate will lag behind initially and not represent your effort for the first half of the interval.
  • Be well rested, fueled, motivated and hydrated for your workout
  • Find your best climb, ideally a steady grade between 2 - 6% but use whatever you have to 'make the watts'
  • If you live in an area void of climbs that's ok because threshold watts on the flat are physiologically close to threshold watts climbing
  • Go as hard as you can for these efforts! Use your powermeter to stay above 98% but not above 104%. If you are able to sustain wattages for your climbing intervals > 104% that means your FTP is probably set too low (and that is a good problem to have :)

Three Example Climbing Workouts:

Here are 3 climbing workouts that start on the shorter side and progress to longer durations and greater total time spent at threshold. Choose the shorter intervals if you're training for climbs less than 15 minutes. Or if you are training for longer climbs (20-60 minutes), start with the shorter intervals and work your way up to the longer ones. 

#1 Supra-Threshold Climbing Workout: 3 x 8 minutes

We say 'supra' because we want to see the athlete achieve average wattages greater than their FTP (or the maximum power that they can sustain for one hour).

Here is real world power, heart rate and gps data from a FasCat Athlete executing the 3 x 8 minute supra-threshold climbing intervals from above:

Notice the steady power up and down the consistent 6% grade hill where the athlete averaged 302 > 304 > 306 watts for a total of 24 minutes of climbing threshold work.

#2 Threshold Climbing Workout: 3 x 15 minutes 

This workout has a 2:1 work to rest ratio, so 15 minutes on, 7.5 minutes off = 45 minutes of threshold work.

Because the fifteen minute intervals are longer efforts than the 3 x 8 minute intervals, the wattages will be lower even if performed as hard as possible [**unless the you've gotten faster].

This lower power is simply how the critical power-duration curve works (1) The total time spent at threshold also increase from 24 minutes [3 x 8] to 45 minutes [3 x 15].

** with a well designed training plan often times we see athletes adapt from week to week. In other words their FTP is literally increasing from week to week following their training plan and they are able to hit higher wattages week to week.

#3 Advanced Threshold Climbing Workout: 2 x 20 minutes:

The infamous 'two by twenty' is close to one of the most difficult climbing workouts in the playbook. Time trialists recognize this threshold workout and the physiology is more or less the same: maximal steady state power for performance bouts > 40 minutes. We prescribe 100- 110% of the athlete's FTP again by the critical power model with FTP being what the athlete can sustain maximally for 60 minutes. We also teach, coach, explain 'full gas' by feel and often times like the 3 x 15 minuters above the athlete is able to achieve wattages greater than tradition zone 4 ranges 98 - 104%.

Here is real world power, heart rate and GPS data from a FasCat Athlete doing the 2 x 20 minute climbing workout from above:

Note the drop off in power in the 2nd half of the second interval while heart rate remained elevated. This indicates he is fatigued and pushing the legs as hard as they will go!


Pacing your climbing intervals is easy with a powermeter but know that you could probably exceed the prescribed wattage for the first interval. When we say 'full gas' and 'as hard as you can' we mean for all the intervals, not just one super good one and 1-2 more that fail to hit the prescribed wattages. Therefore, in practice the first climbing interval may feel easier than the next intervals. By 2nd half of the last interval you should be using your powermeter for motivation to keep your power above the lower end of the prescribed wattage!


Perform climbing workouts to ride faster uphill. Start with a simple 3 x 8 minute climbing interval workout and progress to longer intervals that achieve a greater total time at threshold.

For example:

3 x 15 and then graduate on up to the 2 x 20 minutes.

Execute your climbing intervals as hard as you can by feel and use your powermeter for pacing and motivation. Perform one full gas threshold workout per week along with your sweet spot workouts and see if your power output doesn't increase after 3 - 4 weeks.

About Jake Rytlewski

Jake Rytlewski grew up racing in Michigan at 15 after his Dad picked up cycling as a hobby. Not being able to clip in fast enough before being dropped he quickly found solutions such as double sided mountain bike pedals and track standing. Coaching was always in his blood. He accepted a cycling scholarship to Marian University in 2002 and while there spent a summer racing in Belgium and signed his first pro contract. Jake graduated in 2006 with a degree in sports management and continued to race as a pro for 9 years. He joined FasCat in 2013 and has been coaching full time since. Currently Jake is living the dream in Indiana raising his 3 kids, coaching others to make them faster and to reach their goals and racing in the full time Dad category on Zwift.
