I think you are better off picking a max based on your data, since you have it. Your 4/28 HR looks pretty clean, and I read your max as at least 178 there, maybe ignoring any super short higher spikes.

The recommended test for max is usually a bit shorter because if you are already tired from the 5 mile warmup, you won’t be able to go as hard. If that was the case you could guess slightly higher.

Ken is right to say you should use your data, not the formula. And if your HR data from the run you mention was accurate, Ken's estimate of 178 would be sound. But I don't believe the data from that run. Looking at some other trainings, especially the end of recent o races and your track workouts, it seems obvious to me that your true max is nowhere near the 170s, not unless you're a complete slouch when you race or do workouts at the track, and don't put out a hard effort. Looking at the data as a whole (and ignoring that one day), I would estimate that your true max is around 160.

There are ways in which wrist HR data can be better than chest data, especially in cold weather. But overall the data from the wrist is less trustworthy, even if you ignore the spikes and other noise, of which there's a lot with the wrist.

I mean, if you're planning to use the wrist HR data to do the workout, you should use the wrist HR data to determine the max. It may be wrong, but hopefully it is consistently wrong!

And yes, definitely use your own data. 220-age is an approximation at best.

My worry, looking at a few of Ken's workouts, was that it was not consistently wrong. But some sort of averaging over multiple workouts might be good enough.

Thanks for your comments and input.
I'll do a 5k race this Saturday (Grace Cottage) and will use that to get some current max data.

When did you switch over to the new watch? Maybe I misunderstood, I thought it was just the last couple workouts.

Kenny gave it to me several years ago from his drawer full of surplus Attackpoint watches.
