This week Zwift announced Spring Training – a weekly workout series featuring “6 effective, efficient, achievable workouts that perfectly complement your indoor and outdoor training.”
The series begins April 17 and runs through May 31. Zwift says, “These workouts were built to push you and help you realize your fitness potential —so whether you’re a seasoned pro or kickstarting your fitness journey, you will surely see a fitness boost! Because Indoor Work = Outdoor Results.”

Workout Details & Schedule
Group workout events are scheduled hourly each week. (See the list of upcoming events at zwift.com/events/series/zwift-spring-training-2023.) You can also complete the workouts on your own as on-demand workouts.
April 17-23: Aerobic Rev Up (40 min)

It’s time to rev up your aerobic system for some upcoming intensity! In Stage 1, you’ll complete 20 minutes of “work.” The “work” is split into 2 x 10-minute segments, with 2 x 1-minute surges in each block. You got this!
April 24-30: FTP Booster (40 min)

Stage 2 is all about boosting your ability to ride harder for longer. This workout quickly builds fitness by mixing a tough but controlled effort with 15-second bursts of intensity. Get ready to feel the burn!
May 1-7: Hairpin Wizard (44 min)

Want to get better at short accelerations? Surgey climbs, covering attacks, accelerating out of corners—Stage 3 is here to prepare you to tackle them with ease. This session consists of 2 x 16-minute tempo efforts with a 30-second surge every 3.5 minutes. By incorporating 30-second high-intensity efforts into tempo blocks, you’ll improve your ability to work aerobically for longer periods of time.
May 8-14: Over, Under, and Beyond! (50 min)

Stage 4 is on with one of our favorite workout styles: over-unders! Over-under workouts provide a serious fitness boost by teaching the body to tolerate and clear lactic acid buildup. Your legs might be sizzling, but know that you’re making some profound, positive changes!
May 15-21: VO2 Blast (43 min)

Alright, alright. Stage 5 is here to test your mettle, so before you proceed, take a deep breath and get ready to push your limits. This workout consists of 6 (3 minutes on, 2 minutes off) intervals that progressively get harder.
VO2 max intervals like these are one of the best ways to develop the ability to go harder for longer with less fatigue. But these gains come with a price—some seriously hard sets. Get after it!
May 22-28: Final Send (45 min)

Get ready: Stage 6 lives up to its name! In the Final Send, you’ll work to better your sprint. You can improve your power output and overall speed by training the body to produce energy anaerobically—and this is precisely what stage 6 does. But, similar to VO2 sets, sprint training is no walk in the park. Be ready to suffer in the final stage—your summer self will thank you for the fitness!
Make-Up Days May 29-31
If you missed one or more workouts but want to make sure you complete all six stages, there are 3 make-up days scheduled at the end of the series. During this time, stages will rotate every 30 minutes.
On-Demand Workouts
If you can’t fit a group workout into your schedule, or just prefer to do the workout on your own, all Spring Training workouts are available as “on-demand” workouts from the workout folder. Completing the workout as an on-demand workout counts as completing the stage.

i remember the days when there were like 3 badges a year, now there’s like 3 a month.
Looking forward to spring training!
Should these be done just once per week along with, say several Zone 2 rides?
Depends on your fitness level and goals. Many riders alternate hard and easy days (maybe 3 hard days to 4 easy days each week). If that’s you, you could theoretically do these more than once a week – or do the workout just once, and do other hard rides.
I’m going to give it a go. Coming back from illness and need some boosting and to push myself harder
Can you do this in erg mode?
Yes, these are ERG mode workouts.
Each workout is available for 1 week. Spring trainning is a plan or a isolated workouts? How many times should we do an workout per week?

It’s a series of workouts, so I’d call it a plan… albeit not a complete plan.
For many of us there are other things happening at this time of year; I’ll be outside cycling in training rides, sportives and races as well. One indoors workout a week is just right for me, I’ll save it for a rainy day.
If I hav a look at the duration of the trainings, I’m wondering how these can help me for my IRL rides.
they look more as an introduction to a training plan.
will the workouts be available in zwift after the period or are they limited to this period only? Thank you very much.
Hi, in order to achieve the badge, can we do these workouts on- demand in one week or it is mandatory to do them in each week them are scheduled. I have done yesterday second workout and it looks like I did not advance in achieving the badge. Thanks
Zwift says you can do them on-demand to achieve the badge. If it’s not showing your progress, you should contact Zwift support.
Order shouldn’t matter.
Same here, I just finished the first workout (Aerobic Rev Up) but it still says 0% complete. I guess I will ask support what’s going on.
Me too. Looks like it is not an isolated problem.
Hi Eric,
There seems to be a bug with the progress indicators on the Zwift Home screen for the Spring Training and the Watch The Femmes challenges. It’s been widely reported in the forums, but with no response from Zwift (that I’ve seen). Have you heard anything from your contacts on when it might be fixed?
Thanks Pete
FYI: if you aren’t getting credit on the progress bar for Spring Training Workouts, have no fear! Zwift knows about the issue and is fixing it.
I’ve completed all six sessions and the mission shows as complete on my homescreen, but there’s no badge in my profile. Anyone else have the same issue?
Zwift says I have one workout to do, but I’m sure I did them all. For the life of me I can’t figure out which one shows not complete. I want to check it off but for the life of me can’t figure out which one is missing so I can redo it?
