Acclimatization really underway now.  Did a slightly different session this morning – walked briskly at 6.4kph for 40 minutes then did the usual 10 min run/10 min walk to the end – 90 minutes total.

HR whilst walking at 6.4kph/4mph is now down to 117 (from way over 125) and slowest run at 125 is now up to 7.8kph at 35C/95F.

Today Start: 13.3C/84% humidity; Finish: 35.9C/62%
