psychology The 3 Core Pillars for Sub-20
VO2max Intervals
800m-1200m repeats at 3:45-3:50/km. The aerobic ceiling builders that make 4:00 pace sustainable.
Tempo Runs
5-7 km at 4:10-4:15/km. Lactate threshold work that teaches your body to clear acid while running fast.
Recovery
Easy runs at 5:00-5:30/km and full rest days. Without recovery, there's no adaptation.

5K RACE
Race Week: Trust your training. Go get that sub-20!
route Race Day Split Logic
restaurant Fueling for Sub-20
Before the Race
- • Light meal 2-3 hours prior.
- • Low fiber, easily digestible carbs.
- • Toast with honey or a banana works well.
During the Race
- • No fueling needed for 5K.
- • Just ensure you're well-hydrated before the start.
- • Avoid drinking too much right before.
warning Critical Pitfalls to Avoid
Going Out Too Fast
A 3:50 first km almost guarantees you'll fade badly. Stay controlled and disciplined.
Skipping Recovery Days
Quality training requires quality rest. Easy days make hard days possible.
Too Much Intensity
Every run can't be hard. Save racing for race day, train smart.
Ignoring the Taper
Trust the process and reduce volume before race day. You'll feel restless—that's normal.
Racing Every Workout
Training runs are not races. Save your best efforts for when it counts.
