How Long Until You Can Do 100/100/100 + 10km? Realistic Timelines
Two questions come up again and again: how long until I can do the full Saitama workout, and how long does it take each day? The honest answer to both depends on where you start. Here are realistic numbers.
The short answer
Most people need somewhere between 8 and 32 weeks to build up to the full daily routine:
- Already fit (40+ push-ups, running 5km): about 8–12 weeks.
- Some fitness (10–20 push-ups, running 1–3km): about 12–16 weeks.
- Beginner (under 10 push-ups, not running yet): about 24–32 weeks.
These are ranges, not deadlines. Sleep, age, injuries, and how consistently you train all change the pace. The run usually takes longest, because bones, tendons and feet adapt to running more slowly than muscles adapt to push-ups.
Milestones along the way
Here's when some real plans from the plan generator reach two halfway milestones (50 push-ups and a 5km run a day) and the full goal:
| Starting point | 50 push-ups | 5km run | Full goal |
|---|---|---|---|
| Week number when each daily target is first reached | |||
| Beginner (5 push-ups, no running), 32 weeks | 20 | 21 | 32 |
| Beginner (5 push-ups, no running), 24 weeks | 15 | 16 | 24 |
| Some fitness (10 push-ups, 1km), 16 weeks | 10 | 10 | 16 |
| Active (20 push-ups, 3km), 12 weeks | 7 | 6 | 12 |
| Fit (40 push-ups, 5km), 8 weeks | 3 | 1 | 8 |
Notice the pattern: the halfway milestones arrive around 60% of the way through the plan, not at the midpoint. That's the ease-in curve: gentle increases early, while your body adapts, and bigger ones at the end, once you have a base. If the first weeks feel slow, that's by design.
How long the workout takes each day
Once you reach the full routine, expect roughly:
| Part | Typical time |
|---|---|
| 100 push-ups (in sets) | 10–20 minutes of effort |
| 100 sit-ups (in sets) | 5–15 minutes |
| 100 squats (in sets) | 5–15 minutes |
| 10km run at an easy pace | 50–75 minutes |
| Total | About 1.5–2 hours |
You don't need one big block. Most people spread the reps through the day and do the run in one go. Early in a plan, the whole day takes much less: often 20–40 minutes.
What speeds things up (and what slows them down)
Helps
- Training consistently, rest days included.
- Seven or more hours of sleep and enough food, especially protein.
- Some previous training, even years ago.
- Good technique from day one.
Slows you down
- Starting too high and getting hurt. This costs more time than any slow plan.
- Skipping rest days (see why rest days matter).
- Short sleep, high stress, or illness.
- Being new to running: the 10km usually lags behind the reps.
Behind schedule? Adjust, don't quit
Plans are estimates. If the targets keep getting away from you, don't force it:
- Repeat the current week until it feels manageable.
- Re-test your max and regenerate your plan from your real numbers.
- Choose a longer plan length. Adding 8 weeks is much better than stopping.
Ahead of schedule? Great. You can regenerate with a shorter plan, but keep the rest days.
FAQ
How long does it take to be able to do the Saitama workout?
Usually 8–32 weeks, depending on your starting fitness. Complete beginners should plan on 24 weeks or more; people who already run and can do 40+ push-ups may need only 8–12.
How long does the Saitama workout take per day?
About 1.5–2 hours once you reach the full routine, most of it the 10km run. Earlier in a plan, days are much shorter.
Can I reach 100/100/100 + 10km in 30 days?
Only if you are already close to it. Starting from low numbers, trying to get there in a month greatly raises the risk of injury, especially from the running.
When will I see results from the Saitama workout?
Most people notice higher rep counts and easier runs within 3–6 weeks. Visible changes in fitness usually take a couple of months of consistent training.
