Tiernan McCorry has been competing for 4 years. His best event is the Pyraminx: a personal-best single of 1.39, set at Mayo Cubing 2026, puts him in the top 0.31% of the 130,891 people who have ever been ranked in the event, and 6th in Ireland. Until March 2013, no official Pyraminx solve in the world had been that fast. Across 28 competitions since August 2022, he has put 1,525 official solves on the record across eleven events.

His 3×3 best has come down from 21.56 in August 2022 to 9.13, a 58% improvement. Tiernan has entered 28 competitions, more competitions than 98% of everyone who has ever competed.

The story so far

Competitions

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
