Rainbow Run speed trap location in Forza Horizon 6
The Rainbow Run speed trap sits on Rainbow Bridge in the south-western section of Tokyo City. Its position is easy to miss, so set a destination marker before driving there and use the route guidance to avoid taking a wrong turn.

This is a particularly awkward speed trap because the measurement point comes shortly after a corner. The road also provides only two lanes, while regular traffic can disrupt your run and make it difficult to reach the higher speed targets.

How to approach Rainbow Run
After placing the waypoint, plan your run around the bend rather than trying to accelerate at the last moment. Clearing traffic before the turn can help. Causing a backup or wreck ahead of the corner may leave a cleaner stretch of road for building speed.

Rainbow Run star requirements
- One star: 70 mph
- Two stars: 105 mph
- Three stars: 140 mph or higher

Best car choice for three stars
The “All the Colors” daily challenge does not impose a specific car requirement. However, three stars demands a speed of at least 140 mph, so an S1-class car or higher is recommended for its stronger acceleration and greater top speed.

When the challenge appears
Rainbow Run may be required for a seasonal challenge. It is also part of the “All the Colors” daily challenge in the “Italian Exotics” series for the week beginning August 6, 2026.
