The starting point for all race categories is on BPT Road, just outside Sewri Railway Station on the Harbour Line of Central Railway. Click here for the location.

The Atal Setu Sea Bridge consists of two roads:

• Route A heads towards Panvel (on the left from the start venue). This route is designated for the 42 km and 10 km races.
• Route B comes into Mumbai (on the right from the start venue) and is designated for the 21 km and 5 km races.

Each race starts on the Sewri side and follows its designated route over the sea bridge, turning back on the same side to complete the distance.

The course distances are precisely measured using the Jones Counter Calibrated Cycle method and certified by AIMS.

Runners will begin their race on top of the bridge after ascending the ramps. The distance from the start holding area to the actual race start point is approximately 750 meters, so participants should allow sufficient time to reach the flag-off area.
