+We are excited to announce that next year's Berkeley Math Tournament (BMT)
+will be on Saturday, November 14, 2026, in person at UC Berkeley!
+
+<!-- more -->
+
+BMT is our flagship tournament designed for teams of advanced middle school or
+high school students in mind, but younger students are allowed to participate.
+With BMT we aim to introduce students to math beyond what is taught in the
+classroom, and motivate students to explore math and prepare for future
+mathematical endeavors.
+
+For those curious about the problem style, past contests can be found in our
+[archive](https://berkeley.mt/archive/).
+
+Registration will open soon! To stay informed, keep an eye out for newsletters
+and follow us on social media!
