About the race

It usually runs in late April.

Best if you already have a few races behind you.

Training for it

Give yourself 16 to 20 weeks, starting from being able to run 10K comfortably.

  • Build the long run gradually, to around 30 to 32 km at its peak.
  • Practise your race-day fuelling on long runs.
  • Taper for the last two to three weeks.
