i've looked into it because i am training by pace now at the moment but it's too damn expensive.
Most runners who went for Stryd is when they want to train by power intensity. Stryd is one of the pioneer therefore it has one of the most established way of zoning by power. Need to do Critical Functional power test, machiam like LTHR when we want to zone by LT. Being a foot pod, the other advantage is it can gives instant pace. But if you train by pace intensity, then you miss out the thing they was well known for, i.e train by power intensity.
That's why even when we have power reading on Coros or Garmin, not many runners use that function. They do not have a well developed method of determine Funtional Threshold power with their watch. But I guess it is similar to testing LTHR, agar agar just use Power vs LActate (4 mmol) instead of pace or HR vs Lactate.
I wouldn't want to spend alot on money on it if I am not very sure I am going to train via power intensity for the rest of its life span.
Right now I am using Coros foot pod, which is alot cheaper than Stryd. But it will only work on Coros products and don't have the power intensity training.
LAter then sceen shot my long run splits with HR. Not easy to do without a PC.
