Are you sure, Tom ?
With my horse Ligeira, a partbred arab, I read a 235-238 max. on hills over the

My younger horse, Natasha, I stopped her recently around 212-215 for some hundred
yards on my long hill, and I feel she was about 90-95% of her WORKmax, so I
suggest her HRmax. is not far below 235. All these measurements looked quite
stable (HRM model: V-MAX EHRM basic). Of course they can be inaccurate
nevertheless, but I never had unreasonable readings such as >250.
I suggest there are some elite athletes out there with a HRmax. of +-240. Other
