I’d love to have the ability to set both a watts and a speed target for a ride. This is to use IRL on a time trial, where having both on my computer would be great.
I’ve managed to use the API to set a detailed watts target based on distance/time which is great for racing/turbo training. This is great! But haven’t seen anything about speed targets.
Speed is to dependent on terrain and wind to use as a target.
You can always use a NOTE for speed targets as these are things that you can’t control.
Using a maths model of the physics, including gpx and wind, this isn’t the case. It’s what BestBikeSplit does. Seeing a speed target is more stable over a short time span, whereas watts is far more variable.
How does BBS show the user the speed to use for that split?
Your use case is very pertinent and good info, the added info on how it should / is already displayed would negate a lot of researching and come to a quicker possible solution (if any)
I have a wahoo element. BBS shows both target/actual watts/speed on a screen.
I did look into directly sending a workout to wahoo, and think this allows a workout to have multiple fields as a target. Much like setting both watts and cadence, which is already possible in intervals. I’ve not managed to conquer the wahoo developer cloud API interface yet, and intervals is much easier to use.
You have a screenshot of how it works/look?
Cos I have a Garmin and it only shows watts and hr as secondary.
Not easy to provide a screen shot, unless I go out for an actual ride with BBS workout with a camera.
But very straight forwards. Screen is divided into rectangles with numbers and labels for targets and actual values. I’d assume wahoo looks after that once it has received the target numbers in a workout/plan.
I’m just wanting to set numbers for targets in both power and speed. Nothing more complicated, say like running a maths model to relate the two!
BBS has a Garmin IQ App which shows you what it came up with.

@Simon_Bond I’m not sure what exactly is expected here by the OP. Just displaying what BBS calculated or have Intervals do the math iso BBS?
The math behind this is very advanced. It needs a recent PDC, good terrain information and weather (wind) forecast. And it needs to be an iterative process because you start with a certain wattage estimation and if that turns out to have a time result out of your PDC curve, you need to start over to find a feasible wattage target. That wattage target then needs to be converted to a speed taking wind and terrain in account.
The calculations are, for my POV, outside the scope of Intervals. The display of the BBS instructions is something that needs to be handled at the device level. So, not quit sure where intervals should come in here?
Or am I missing something here?
I’ve done the maths myself, outside of intervals. A home-made alternative to BBS. The output is a data set with set of target power, and speed, for each fixed distance along the route, all tailored to the course and conditions I’m riding.
I want to be able to put those target values into workout that has targets of both power and speed, so I can use the maths I’ve done above when actually riding a TT. I’ve done this already for just distance and power target as Intervals already does this, and then sends it to Wahoo. I just want to add in speed on top of this as as target.
So, the native text workout might look like
with about 160 such lines for a 10 miler.
Garmin has a 50 step limit. Does wahoo?
Also - not asking for you to bring a camera. Just take a photo of the screen or even link to how it looks on a wahoo.
Pretty sure this isn’t a new thing from bbs.
And from what I reading. You just want text notes.
But again. Garmin has 50step limit. So Maybe wahoo has similar restrictions??
