My heat training for New York started today!


Follow my progress as I acclimatize myself to run through New York’s hot and humid summer in the 3100 mile race starting June 15th.

Here at home in Sanday, Orkney the temp this morning was just 10 deg C/50F

I did a 90 minute session in my heat chamber.  At the finish the temp was 35.9C/96.6F and 61% humidity.

I was doing a MAF run and walk. HR rose by 30 bpm when walking at 6.4kph and run speed had to fall from over 10kph down to 8 to keep HR at 125 at the maximum temperature.
