In order to start boosting up the humidity (it tends to fall as the heat from the halogen heaters rises) I put the humidifier on a time clock and it came on 2½ hours before I started.  I’ll starting making it earlier and earlier to keep the humidity high enough.

Today the session was less of a mental ‘shock’ but still a physical shock as revealed by the stats.  Once th etemp is over 25C and especially over 30C the impact of run pace is really dramatic.

Starting temp/humidity 12.4C/74%; Finishing 36.6C/64%

Lowest running speed at a HR of 125 was 7.6kph so lower than yesterday!
