Training Tips
Run Intervals at 5K Pace or Faster
400m and 800m repeats at 6:25–6:20/mi teach your body to sustain the effort required. A classic session: 6 x 800m at goal pace with 90-second recoveries.
Add One Tempo Run Per Week
A 20–25 minute tempo run at comfortably hard effort (roughly 6:40–6:45/mi) builds the lactate threshold that underpins every fast 5K.
Do Not Neglect Easy Miles
The bulk of your weekly mileage should feel genuinely easy. Easy miles build aerobic capacity and speed recovery between hard sessions — they are not junk miles.
Start Controlled
The first kilometre of a 5K always feels easy. Resist it. Going out at 6:10 pace will cost you the final mile. Aim to run the last kilometre faster than the first.
Practice Race-Day Conditions
Do at least one workout per week outdoors and include strides (6 x 20-second pickups at faster than race pace) after easy runs to sharpen leg turnover.
Prioritise Recovery
Sub-20 requires consistency over weeks and months. Sleep, nutrition, and rest days matter as much as the hard sessions. Injury prevention is training too.
