10 kliks? That's not too bad. There are still four months for
him to train.
I assume that he's run at least 5km before in school road runs,
etc? If so, then it's not too difficult to train him up to 10km.
Just start him off with 2.4km and then slowly ramp up the distance
week by week.
yah... should be enuff time....
when i did my jogging, i was able to jog for 15km after 2-3
mths (2-3x a wk)... but running is more difficult lah...
