Half marathon

The next half marathon race is in two months' time, and I had signed up for it, while I'm supposed to start training for it now, I haven't really started yet. I had only clocked the furthest 4km? That's not even 1/5 of the race's distance!

The longest trainig run I did was 15km before a previous race, I don't know whether I can clock this much distance for each training session this time. Maybe there's still time, hopefully, I can do better.
