Beginners: your first 5K in 8 weeks
At the start it isn't your lungs that limit you but your tendons and joints, which adapt more slowly than your heart. So you alternate running and walking and stretch the running blocks gradually. Three sessions a week are enough, with a rest day between them. The pace is right if you can still speak in full sentences.
- Weeks 1–2: 8 × 1 min running, 2 min walking
- Weeks 3–4: 6 × 2 min running, 2 min walking
- Weeks 5–6: 5 × 4 min running, 1 min walking
- Week 7: 2 × 10 min running, 2 min walking
- Week 8: 5 km or 30–40 minutes without stopping
Starting to run at 40, 50 or 60
The structure stays the same; it just may take longer. Repeat a week if it felt hard. Easy cycling, swimming or brisk walking between runs spares your joints. If you have a cardiovascular condition or are returning after a long break, talk to your doctor first.
Finishing 10K: the step up from 5K
If you can run 5K without stopping, 10K is six to eight weeks away. Add about a kilometre to one run each week and keep the others short and easy. Once that run reaches 10 to 12 km, race day is no longer a leap.
A 10K in 6, 8 or 12 weeks
Six weeks is enough if you already run three times a week and can cover 10K; the block is then purely about pace. Eight weeks is the usual block for a new personal best. You need twelve for big jumps, say from 50 to 45 minutes, or if you still have to build the distance. Four weeks won't make you faster; they only sharpen what's already there.
Getting faster: intervals and tempo runs
Over 5K, what counts is pace close to your VO2max; over 10K, threshold joins in. One hard session a week is enough down to about 50 minutes over 10K, and faster goals can take two. Everything in between stays easy, or the hard sessions lose their edge.
- Intervals: 400 m to 1 km at 5K pace, with 90 s to 2 min of jogging
- Tempo run: 15–30 minutes at threshold
- Strides: 4–6 × 20 seconds at the end of easy runs, beginners included
The last week and race day
For 5K and 10K, one lighter week before the race is enough. Volume drops by about a third, and two days out you still run a few short segments at race pace. Warm up properly: ten minutes of easy jogging, then a few strides. The most common mistake is the first kilometre. Run it at goal pace, not faster.
- No fueling needed: a normal breakfast two to three hours before the start
- New shoes and new gels stay at home
What YOUB does differently from a fixed plan
A fixed plan doesn't know your week. YOUB plans with you in the chat, knows your calendar, sleep and recovery, and moves sessions when life gets in the way. Workouts arrive with pace targets from your own zones on Garmin, COROS, Suunto and Wahoo. An Apple Watch delivers your runs through Apple Health, and you follow the planned sessions in the app.
