The run is an out and back on the same road as the bike course.


In order to facilitate a safe racing environment we have come up with the following distancing and hygiene rules:

Parents and supporters will not be allowed in the transition area and no outside assistance by parents or supporters will be permitted during the race. Violation of these rules will lead to disqualification of the athlete. We have been involved in many junior races over the past years in different roles and we know that the juniors are perfectly capable of organizing themselves without the assistance of their parents.

Our staff will be available on-site to assist junior athletes with questions and there will be pre-race announcements and the mandatory race briefing prior to the start as well. We encourage you to cheer on your children during the race and help contribute to the positive and relaxed atmosphere that the Tri Dash Bangkok series has become known for.
