I tried the 'talk test' and worked fine at that pace. However, yesterday I had to run on a treadmill (IÂ´m out of town in business) at the hotelÂ´s gym. Since it was too hot (IÂ´m in Rio and the ar-conditioned of the gym was broken) I ran at a slower pace.
So: Day 3 - 30 min easy run
Distance covered: 4,6k
Today I return to Sao Paulo and I donÂ´t know if IÂ´ll have time for tonightÂ´s run.
Anyway, IÂ´ll keep you posted.
