Mt Whitney Zone Forums General Discussion how would you compare half dome hike to whitney dayhike?

Hi Ponzy,

I have never seen it recommended that interval training be conducted at maximum heart rate. I think your target heart rate should be ~75% to 85% of your max. I suggest doing the interval at whatever your heart rate is such that you can sustain the interval. Try not to target a certain rate until you have a better idea as to your level of training.
