20 km of Brussels 2026: traffic, parking and transport on 31 May - Seety
20 km of Brussels 2026: traffic, parking and transport on 31 May
11-05-2026 · 5 min · Laura
The 20 km of Brussels 2026 takes place on Sunday 31 May 2026 from the Esplanade du Cinquantenaire. Whether you are running, accompanying a participant or simply trying to move around Brussels that day, you need to plan ahead: major road closures, no parking along the route, difficult access near Cinquantenaire and heavy disruption for a large part of the day.
The easiest mistake is trying to find a street space near the race. In practice, that rarely works. The better approach is to pick an off-street parking option before you arrive, then finish on foot or with public transport. That is exactly where the Seety app becomes useful: it lets you quickly spot parking options around the race zone.
Key takeaway: on 31 May, do not rely on on-street parking around the route. Open Seety, compare parking options around your access point and decide how you want to arrive before you start driving.
Key facts in 30 seconds
Date: Sunday 31 May 2026.
Start / finish: Cinquantenaire Park.
Distance: 20.1 km.
Route closure starts: 8:30 on the main roads concerned.
Progressive reopening: from 12:00 depending on the area.
Parking on the route: forbidden, with possible towing.
The 2026 route at a glance
The official 20 km of Brussels route passes through major parts of the capital, including Schuman, Belliard, Louise, Bois de la Cambre, Avenue Franklin Roosevelt, Chaussée de la Hulpe, Boulevard du Souverain and Avenue de Tervueren.
This means that a large part of south-east and central Brussels will be much harder to reach by car during the morning and early afternoon.
Traffic: which roads close and when?
According to the official mobility page, all roads on the route close from 8:30 in the morning. They then reopen progressively after the runners and the clean-up teams have passed.
The official indicative timings are:
Rue Belliard around 12:00;
Avenue Louise around 13:00;
Avenue Franklin Roosevelt around 14:00;
Boulevard du Souverain around 15:00;
Avenue de Tervueren around 16:00.
If you absolutely need to cross Brussels that day, it is better to prepare a bypass route instead of hoping for an earlier reopening.
Parking: forget on-street parking, use Seety to target off-street options
The organisers are very clear: parking is forbidden along all roads used by the race and vehicles in violation can be removed. Trying to find a street spot near Cinquantenaire is therefore the wrong strategy.
The most efficient approach is to look for off-street parking around your arrival point. With Seety, you can:
see parking options around the route before you leave;
choose a parking area based on the side of Brussels you are arriving from;
avoid circling through closed or saturated streets;
decide whether it is easier to finish on foot or with a short STIB connection.
Two examples to check first in Seety
As a starting point, look at these two areas in the app:
Rue du Noyer 284, 1030 Brussels;
Lutherstraat 58, 1000 Brussels.
These examples do not replace a live check. The right move is to open Seety on race day and compare the parking options that still make sense for your arrival time and your access route into Brussels.
Reaching the start without stress
For access to the start area, the organisers first recommend public transport. The most useful stations are:
Mérode: metro 1 and 5, tram 81;
Schuman: metro 1 and 5;
Montgomery: trams 7 and 25.
Elisabeth Agustín
If you decide to park a bit further away using Seety, the most reliable logic is usually:
reach a parking option outside the most disrupted zone;
walk if the distance is reasonable;
otherwise finish with metro or tram to Mérode, Schuman or Montgomery.
For many drivers, that combination is more reliable than trying to approach Cinquantenaire by car until the very last moment.
Crossings that remain possible through the route
The organisers also mention several passages that still allow entry or exit from inside the route, notably via:
the Trône tunnel;
the Louise tunnel;
Place Stéphanie;
Rue du Bailli;
Chaussée de Vleurgat;
the E411;
the Montgomery tunnel.
In practice, these passages can help if you come from a specific side of Brussels, but they do not change the main conclusion: traffic will remain slow and the race area will stay difficult to approach.
A simple strategy for runners and supporters
If you want to reduce stress on 31 May, the safest method is this:
open Seety before leaving;
compare several parking options around your access zone;
keep a fallback option if your first choice is too busy;
finish the trip with metro, tram or on foot.
This works better than last-minute street parking near Cinquantenaire, especially between 8:30 and early afternoon.
