Running power calculator

Hi Trux,

This is not what I meant. I'm looking for a Running power calculator for Garmin to convert pace to power at the time you program the workout into your watch, e.g. If my training program says 30' at 5:35 min/km, that I know 'ah, that's X watts in Running power'. I can't use the regular calculator because Running power from Garmin differs quite a bit from Stryd, Coros and Apple.

If you want to create a workout based on Running Power, you can do it, without the need of any calculator. Just set the target running power, and then when doing the workout, stay within the target window. Do not base your running power workouts on pace, base them on the power. The needed power depends on more factors than just the pace (slope grade, wind, terrain, ...)

But how do I know the Power Target if my trainingplan is set to pace (like most trainingplans do). I.e. Interval training 8x2' at 4:45 m/km... what running power goal do I set? 

Or if I need to run an average speed in a race for a PB? I.e. 10k in 50’ =  5:00 m/km.

I know RP depends on several factors, which is why I use it, it takes into account wind and slope rather than just running at pace and blowing myself up in the first few miles on a hilly course.

A pace-power converter would be very helpful then.

Now my only baseline is my threshold power and have to (educated)guess my Power Targets on that for specific Interval trainings and Race Pace.

Have you looked at the calculator I mentioned in my first post? Something like that, but for Garmin Running Power. I can not use that converter, because you calculate RP very differently than Stryd, Coros and Apple, but that's okay if you consistently use the same metrics.

You could also ask "and how do I know the Pace target?". You need to start with a target, and then see how it goes, and adjusting it the accordignly.

You best start with correctly establishing you HR zones, then doing a few runs based on the HR. And once you have reliable RHR, Max HR, LTHR, and have also well defined power zones after those runs, you can start training by power zones, without the need of any power calculator.

Hi Trux,

I have an RHR, Max HR and LTHR and well defined heart rate and power zones. My question remains that if a training plan (like all Garmin plans) is based on pace, how can I set the correct power target without a proper converter for interval training? This also applies to race pace?

The response that I don't need it is incorrect, so I don't think you understand my question. I'll leave it at that and go with the educated guess. Thanks for your response

Oppositely I think you do not understand the purpose of a pace based, HR-based, and power based workouts. If you have a training plan or a workout based on pace, you should run in that way that your pace (not power) stays close to the target pace. If you have a HR-based workout, you try keeping the HR near the target. And only if you have a power based workout, you should watch your running power and trying to stay close to the target. In other words, there is no need for converting your pace to running power when your target is certain pace.
