HR zones never seam to tally up for me. If im going steady my HR is about 150-155 and if im going at it then it hovers around 175. If i look on sites etc then 155 is supposed to be a hard pace. I would struggle to run at 130 etc. Maybe its because im tall, but they never make much sense!
Dynamic i have to pick up our race number and chip from inside hotel on morning parking will be in streets and car parks ( i suspect ) we have a 155 mile journey taking 2.3'4 hours or more of 155 miles we'll leave at 5:30 then one cat relax and drink coffee good luck what ever
