db9 is/was the local competition of Bouldercentrum Delfts Bleau! A competition with 20 brand new boulders graded 5 to 7b+ , with a maximum of 9 attempts to top each of them. Scoring is based on the IFSC format, where the number of tops, the number of zones and the number of attempts you needed to reach these tops and zones determine your score. You take care of filling out your score form your self and hand in this score form after finishing your last boulder. The last competition date in this format was held Friday evening 17 April 2026. After years and years (13!) of db9’s it’s time for a new format. We’re in the midst of developing this new comp with working titel db9 2.0.
Date for db9 2.0 has been set: FRIDAY 18 SEPTEMBER 2026.
This won’t change with the new comp: Nearly all competition boulders will be removed on Sunday after opening hours. Make sure you don’t miss out! If you truly cannot make it on Friday, don’t miss your chance on Saturday or Sunday.
