About The Princess Maha Chakri Sirindhorn Cup Tour of Thailand

The Princess Maha Chakri Sirindhorn Cup Tour of Thailand is a multi-day cycling stage race held each spring on Thailand's continental calendar. Named for the Thai princess and longtime cycling patron, the race typically runs five days through varied terrain in late March.

Named in honor of Princess Maha Chakri Sirindhorn, a longtime supporter of cycling in Thailand.

This is one of the few stage races contested in tropical conditions, where the heat and humidity of Southeast Asia become tactical factors as significant as the route itself. The race draws a mix of Asian continental teams and European squads looking for early-season racing miles, creating an unpredictable blend of climbers, sprinters, and riders still finding form after the winter.

The Princess Maha Chakri Sirindhorn Cup Tour of Thailand route

The route typically mixes flat stages suited to sprinters with rolling or hilly terrain that can split the general classification. Time gaps tend to open on any stage with sustained climbing, though the heat often plays a larger role than gradient alone. Breakaways can survive when the peloton struggles with pace in the afternoon sun, and the general classification is usually decided by whoever manages recovery and hydration best across the week. Expect at least one sprint finish, one or two stages with climbing that matters, and possibly a short time trial. The race rarely follows a fixed loop, so the specific towns and roads change, but the tropical conditions and the mix of terrain remain constant.
