TT tune up


How many have completed this plan? Just at end of week 5 and the power requirements in some workouts (I.e ac plus ss) have shot up massively. The work outs up to this point have been ok, not hugely challenging. Ftp set and tested.

I know I can drop difficulty (and I will). But I wondered if these workouts are just hitting my weak areas or if they are almost unachievable!!


I’ve heard that training plan gets very hard after the base weeks. Yes, almost to the point of being not doable. But I bet if you suffer, you will get faster.

Its an advanced plan for a reason, as is Crit Crusher. The 2nd to last week is brutal but manageable.

I’m on week 8 of this plan and I found there was a bit of a step change in week 5 regarding the Z6 stuff ramping up to 150% of FTP, I quit my first ever workout in this week after thinking I had been making good progress to that point, I failed the cruise intervals in week 5 also, and then missed two more due to work/holiday and the inflexibility of the plan so that was a poor week for me, I was dreading week 6!

I’ve completed every workout since, although missed a few stars on more high power Z6 stuff in week 6 and 7

I’ve completed the AC workout for week 8 and took every star on that one, and feeling confident of completing the 4 remaining workouts without missing any more stars.

Currently 41/49 workouts, 672 stars. 876 mile, 41h49m, 28780kcals!

Best of luck with the rest of your plan!


Thanks for your reply.

I’ve had the same kind of end to the plan.

Also in week 8. 2 workouts completed so far.

I had to drop the % on a few of the power intervals. But although the difficulty level has increased I’ve got although all the workouts, so far.

A big well done to both of you :smiley:

I was lucky to have realized early on to approach every workout with 100% commitment. The “Cruise intervals” are deceptively named and are the ones most people (myself included) fail on.

I was also grateful to come into the plan relatively fit at the end of a solid 1.5 month block with plenty of top-end. It was also of great help to skip the optional workouts when I felt I needed a bit of extra recovery. Finishing the plan feels great!

I’ve had little to no struggle with the first 4 weeks at current FTP. However, week 5 power interval and anaerobic capacity workouts at same FTP have proven quite challenging for me (unable to finish high power intervals without dropping FTP in-game and/or pausing workout during recovery interval to keep me from blowing up). I do enjoy the challenge, but definitely need to work on improving my AC. Cruise intervals are tough but doable at current FTP. I am going to stick with it and see this program through to the finish! Started week 6 today. Any thoughts/suggestions on improving one’s AC? I’m thinking just incorporating more AC interval training on a weekly basis would be recommended!


Yes I agree - the first sessions in 4 years of zwifting that battered me into submission and ground to a halt.
Its a shame as they seem just a little too hard in weeks 5 or 6 - the otherworkouts seem to work as you ‘trust’ the coach who designed them and are rewarded with a nicely climbing FTP.
The other trick is not to retest your FTP after 3 or 4 weeks as it will go up and compound the issues.

Having said that I got some PBs on 25 and 50mi TT on the road so not all bad…

Currently working my way through TT tune up - the specific workouts are expiring on a very tight programme. Id forgotten how annoying this was.

IS there a way to do a workout that has expired by 4 hours?

Some of the plans have 6 workouts per week , so in the real world (you know the one with real families, and the one where we earn money to pay our Zwift subscriptions…)
you can’t always stick to the arbitrary rules and want a bit more flex in the schedule.
In the 6 week and 12 week FTP this isn’t an issue as they are in the workout section… but in for example TT tune up AFAIK there is not a get-around?
Or put another way, Ive paid for that session so its up to me not you when I do it…

@Richard_Shaw1 is mildly frustrating, no workaround I’m aware of. Perhaps recreate that workout manually on Zwift being one solution albeit a little more time consuming.

Omg, just started week 6 and nearly died on AC + sweet spot #1. Be warned! Hardest workout ive ever done on Zwift including racing. Cadence down to 50, HR maxed at 182!

Genuinely scared of what’s to come in the remaining weeks.


I’m on last week. The “Power Intervals” & “AC+ Sweet Spot” starting week 5/6 are very very hard, probably doable only if the anaerobic is your strong point.
I’ve always succeeded the first intervals but the recovery are too short to recover enough. The “AC+Sweet Spot” are decresing so by passing the second to recover, the last is doable.
But the “Power Intervals” are even harder and I’ve always dropped at 90%.
I had no difficulty for the rest, the “Cruise intervals” are tiring but easy to complete

Really, enjoying this training plan, agree the first 4 weeks are all about laying a good foundation. For the last 4. Power intervals are my weakness and boy are they tough in weeks 5 and 6. But just completed Pi#3 week 7 and felt much better than I expected. My other comment is my legs always feel tied, when I start the warm up, but feel good after 5 minutes.

Any suggestions for my next plan, other than an Ftp test? Has any one done TT Tune up, back to back?
