Every March, 400 crews of eight are pitted against each other in the Head of the River Race along the Thames Championship Course from Mortlake to Putney (the Boat Race route in reverse). Participation has grown significantly since the first race in 1926—what started out as 21 crews made up of Cambridge and Tidesway oarsmen has since increased to 400 crews from all over the world. The competition starts at 1.30 pm and lasts for about two hours. If you’re waiting at the finish line (Putney Bridge), the first boat should make its way there in about 20 minutes.
Organisers have set the provisional date of the 2019 race for Sunday, March 30th.
