1.25 HP brushless motor · 8.7 mph (14 km/h) top speed · no incline · 120 x 45 cm deck · 130 kg max user · folds nearly flat to 14 cm · 65 dB · 41 kg (lightest) · rated for 5 hours a week
The Domyos Compact Run 100 is the storage champion of Decathlon’s range. It folds nearly flat to just 14 cm, the lowest folded height of any Domyos, and at 41 kg it is also the lightest, so it is the easiest to move and tuck away. If your treadmill has to disappear under a bed or behind a sofa between sessions, this is the one built for the job. It carries a best-seller badge, a 4.7-star rating from 343 owners and a RunRank of 4.0 out of 5.
The trade-off for that flat fold is simple: there is no incline and the deck is short. The Compact Run 100 is a walking and light-running machine for tight spaces, not a training tool. Within those limits, at £499.99 with app connectivity and cushioning included, it is good value, which is exactly where its strongest pillar scores sit.
Who the Compact Run 100 is for
A good fit if you
- Need the flattest, lightest treadmill to store and move
- Mostly walk or run shorter, gentler sessions
- Want app connectivity and cushioning at £499.99
- Live in a flat or small home with limited space
- Like following Kinomap or Zwift sessions
Look elsewhere if you
- Want an incline for hill or interval work
- Need a longer deck for a full running stride
- Are sensitive to noise (this is the loudest model)
- Run faster or longer than gentle sessions
If storage is your single biggest constraint, this is the Domyos to buy. If you can spare the under-bed depth and want an incline, the Run 500 is the same price and the more capable machine.

Key features
Folds nearly flat to 14 cm
This is the headline. Folded down to L150 x W75 x H14 cm, the Compact Run 100 slides under almost any bed or stands neatly in a gap a thicker treadmill could not fit. No other Domyos comes close on folded height, and for small homes that single number is often the whole decision.
The lightest machine in the range
At 41 kg it is significantly lighter than everything else here, so moving it in and out of storage is genuinely a one-person, no-fuss job. Small transport wheels help, but it is light enough that the weight rarely becomes an issue in the first place.
App connectivity and cushioning included
Despite the budget-friendly price, it keeps the useful features: Bluetooth and ANT+ with FTMS for Kinomap, Zwift and E-Connected, a USB port, heart rate belt compatibility, a magnetic remote and 30 programmes across calorie, endurance and interval categories. Four elastomer cushioning pads soften each step. That is why its Value and Features pillars are its strongest.
No incline, short deck, more noise
The compromises are clear. There is no incline at all, the 120 x 45 cm deck is the shortest in the range, and at 65 dB it is the loudest Domyos. None of those rule it out for walking and gentle running, but they do define it as a space-saver rather than an all-rounder. If any of them matters to you, weigh it carefully before buying.
How it compares to the rest of the range
Compact Run 100 vs Run 500
Both cost £499.99, so this is the key choice. The Run 500 adds a 10% incline, a faster top speed and a longer deck, and folds to a still-low 27 cm. The Compact Run 100 trades the incline away to fold nearly flat to 14 cm and weigh just 41 kg. Choose the Run 500 unless the tightest possible storage genuinely outranks having an incline.
Compact Run 100 vs T520B
For a similar budget, the Compact Run 100 is the more flexible buy than the T520B: it is cheaper, folds far flatter, weighs less and adds the app connectivity the T520B lacks entirely. The T520B’s only edge is its 10% incline. If you do not need that incline, the Compact Run 100 is the better value of the two.
The verdict
The Compact Run 100 does one thing better than any other Domyos: it disappears. A 14 cm fold, 41 kg weight and app connectivity at £499.99 make it the obvious pick for flats and small homes where storage rules everything. Just go in clear-eyed about the lack of incline, the short deck and the higher noise. For a space-conscious walker or light runner, it is a smart, good-value choice.
Frequently asked questions
How small does the Compact Run 100 fold?
It folds nearly flat to L150 x W75 x H14 cm. The 14 cm folded height is the lowest in the Domyos range and slides under most beds, which is the machine’s main appeal.
Does the Compact Run 100 have an incline?
No, it has a fixed flat deck with no incline. If you want hill or interval training, the Run 500 offers a 10% motorised incline for the same price.
Is the Compact Run 100 good for running?
It suits walking and lighter running up to 8.7 mph (14 km/h). The short 120 x 45 cm deck and lack of incline make it a space-saver for gentle sessions rather than a machine for serious training.
Is it noisy?
It is the loudest in the range at 65 dB at top speed. That is fine in most homes, but if low noise is a priority the T900D at 52 dB is much quieter.
Does it work with fitness apps?
Yes. It has Bluetooth and ANT+ with FTMS, so it connects to Kinomap, Zwift and E-Connected, plus a compatible heart rate belt and a USB port.
