Training for a ruck march
Twelve weeks from ordinary fitness to a 20 km event under load, and what changes for multi-day marches.

An event is the best thing that can happen to your training, because it converts a vague intention to walk more into a deadline with a distance attached. It is also where people injure themselves, by compressing twelve weeks of preparation into four.
Work backwards from the requirement
Find out three things before planning anything: the distance, the required pack weight, and the cut-off time if there is one. A 20 km event with no weight requirement and no cut-off is a different problem from a 20 km event at 16 kg in under four hours.
Then work back. You want to arrive at the start line having already done, in training, roughly 75 to 80% of the event distance at the full event weight. Not the whole distance — that is the event's job — but enough that nothing on the day is a surprise.
A twelve-week shape
| Weeks | Focus | Long ruck reaches |
|---|---|---|
| 1–3 | Build the habit. Comfortable weight, comfortable distance. | 8–10 km |
| 4 | Deload. Change nothing. | Hold |
| 5–7 | Add weight toward event weight. Distance holds. | 10–12 km |
| 8 | Deload. | Hold |
| 9–11 | Add distance at event weight. Practise nutrition and kit. | 14–16 km |
| 12 | Taper. Short and easy. Nothing new. | 5–8 km |
The structure matters more than the exact numbers: build the habit, then the weight, then the distance, with a deload every fourth week and a genuine taper at the end.
Enter where you are and the event's weight and distance, and get a week-by-week plan that never adds both at once and holds every fourth week.

Full dress rehearsal, three weeks out
One long ruck at full event weight, in the exact boots, socks and pack you will use, with the food you plan to eat, starting at the same time of day. Everything that will go wrong on the day goes wrong here instead, while there is still time to fix it.
Nothing new on event day. Not shoes, not socks, not a pack, not an energy gel you have never tried. This rule sounds obvious and is broken constantly.
Multi-day marches
Events like the Nijmegen Vierdaagse — four consecutive days of 30 to 50 km — are a different problem. The limiting factor is not fitness on day one, it is your feet on day three.
- Train back-to-back days. A moderate Saturday followed by a moderate Sunday teaches you more than one heroic Saturday.
- Practise recovery: what you eat afterwards, how you treat your feet, how you sleep.
- Rehearse foot care obsessively. Multi-day events are won and lost on blister management.
- Bring more socks than you think you need.
Common mistakes
| Mistake | What happens |
|---|---|
| Starting eight weeks out for a heavy event | Weight and distance rise together; something breaks around week five |
| Training only long, slow rucks | No practice at event pace; the cut-off arrives faster than expected |
| New boots inside a month of the event | Blisters on the day, in shoes that never had time to break in |
| Skipping the taper | Arriving tired at a start line you spent three months preparing for |
| Never practising nutrition | Discovering on the day that the gels disagree with you |
The last week
Do less. The taper is not a loss of fitness — the training is already in you, and the last week is where it consolidates. Keep moving, keep it short and light, sort your kit early, and sleep.
The day itself is mostly logistics and patience. Start slower than feels right, deal with hot spots the moment they appear, eat before you are hungry and drink before you are thirsty.
