Which VO2 alternative to Katahdin?

I have this workout scheduled for tomorrow. It seems very overly complicated for an outside workout. Can I just replace it with something of a similar PL, but of more standard intervals without loosing out on something special about this workout?

I think you can probably use the workout search tool to find what you need.

Select VO2 and then duration of 1 hour & 1:15.

Then (for the purpose of finding a simplified workout that’s easier to execute outdoors) select type as ‘traditional’.

Then select PL as 3 and 4 only to further narrow your search.

You’ll be presented with a range of workouts. If it were me, I’d look to try and replicate the amount of time in zone at a similar % of FTP, but taking account that this workout has quite tough ‘rest’ between intervals at 88% so if you’re not doing that, you’ll need to compensate with a bit more time in zone.

NB you’ll not be able to exactly replicate the stimulus because it appears this workout is offering hard VO2 with a degree of ‘under / over’ due to the aforementioned 88% - so going with an easier to execute outdoors option will likely mean opting for a more traditional type interval structure.

So for example, you current prescribed workout (Katahdin-1) shows 4 sets of 8x15 seconds at 125% of FTP. That’s a total of 8 minutes at that percentage - albeit split over 4 sets and with ‘rest’ at 88% which is quite tough.

I’d probably opt for something like either;

Bashful-1 (PL 3.7) - 3 sets of 5 x 1 minute intervals at 125% FTP (total 15 minutes in zone which is more than Katahdin-1 but without the tougher 88% floating rest between shorter intervals)

Or

Boltinghouse (PL 4.4) - 3 sets of 5 x 1 minute to 1:20 intervals between 120% and 125%.

Same rest periods between intervals and sets as Bashful but slightly tougher due to some of the intervals being a few seconds longer.

I’d say the second option is probably the pick of the two for me, but it entirely depends on how your feeling and where your progression is at - because if the jump to Katahdin-1 was already challenging you’d possibly be better opting for Bashful-1 and then you can always add on another interval or 2 if for some reason it feels like you have more left in the tank.

Good luck :crossed_fingers:

Great, thank you so much! Boltinghouse looks fine, I’ll go with that one :grin:

Hey @JoPage!

You can also quickly choose a Workout Alternate :slight_smile:

No, Workout Alternate won’t work in this instance. That’s the biggest flaw with that feature, you will most of the time only get other workouts in the same format. If you are interested in workouts training the same energy system, but in a different workout format you have to find it manually.

To use JoPage’s example. He is looking for a workout that’s not float sets. Checking Workout Alternates here just gives 60+ other float set workouts.

Thank you @Caro.Gomez-Villafane appreciate your answer but, as @Torneng says, workout alternatives actually just gives me the same option, in it’s various forms, see below

Note, these are all showing as inside workouts as, as we all know, you can’t select workout alternatives for outside workouts, you have to change it to inside, select what you want and then change back to outside (I have mentioned this in the suggested improvements thread)

In addition, my question was also focused on why the system has given me this particular workout format and if, by changing to something else, I will be loosing out on a specific adaption….I will then need to weigh up whether trying to execute this outside it worth it compared to executing something of an easier format like Boltinghouse suggested above. I use a fenix watch so don’t have a lovely graph to follow and it makes it hard to anticipate what is coming next. I tend to memorise the workout in advance so I don’t get taken by surprise but when there is a lot of little changes, that is difficult to do.

In addition, could you possibly answer…..does the system build a training plan based on the rider being indoors primarily, and then just give the same workouts outside if the rider selects to do all their training outside, or does the system recognise that outside work has limitations with workout execution?

@Torneng spot on with everything…..except that I’m a she, not a he :sweat_smile:

I see what you mean :slight_smile:

You won’t be losing out on a specific adaptation if you’re manually choosing a similar workout that’s not as complicated. The goal is to spend time at “x” for what’s scheduled for the day.

In this case, I can see how Workout Alternates still have tricky workouts for outside. However, if you do attempt a ride with lots of variation and short intervals, don’t get too hung up on perfect compliance, as riding outside is always less consistent than riding indoors, and the quality of your work won’t suffer too much as a result.

The system picks the best workout for the day, and that workout has an Indoor/Outside version. The thing is that sometimes the picked workout is more complicated to complete outside than inside for many reasons. That’s why, when completing workouts outside, it’s important to remember the intention of the type of workout rather than exact compliance.

If I’m doing a workout like Katahdin outside I just go really hard for the short spikes and ignore the power targets on the spikes. Is that what you would recommend? Or should I find something easier to properly execute outside like the original poster did?

@UWDawgs sorry for the late reply on this one!!!

Katahdin is totally doable outside :slight_smile: It may just be more difficult for someone who’s not as experienced in completing structured training outside..

A good tip for this type of workout is to try and see what cadence and gearing combo aligns with the power target (you can test this during warm-up).

For example, if you have to hit 350 power for your overs, you can quickly find the cadence and gearing that gets you there. Once you figure that out and get to the over-unders, you can “cheat” and know that if you shift up twice, that’s your over, and if you shift down twice, that’s your under (while doing this, try to hold a certain RPM).
