Requirement

4. Learn the disciplines your format uses

Required

All of one option, matching the format you chose in requirement 3(d). Each option is built from the same swimming, biking and running blocks.

Note. The four options are three blocks recombined (swimming, biking, running), and the badge prints each block in the same words wherever it appears. Until you answer the format question this page shows the biking block three times and the running block three times, because all four options are still live.

What this is made of

4(A). Option A, Triathlon: swimming, biking and running
4(B). Option B, Duathlon: biking and running
4(C). Option C, Aquathlon: swimming and running
4(D). Option D, Aquabike: swimming and biking
