ABOUT TJ:
TJ Tollakson is the original Dimond creator and the accomplished CEO of Ruster Sports/ Dimond Bikes. Tollakson began racing in 2001 and quickly proved himself a force to be reckoned with on the bike course. TJ is a proud husband and father to 3 children. You can usually find him pounding the pavement in Des Moines, IA or tinkering with his newest idea at the Dimond Bikes headquarters.

TJ has 10 Ironman podium finishes under his belt, with his favorite being his Mont Tremblant victory. After a bumpy road filled with surgeries and numerous setbacks, TJ used this race to prove he was still at his prime and leads the pack. One of his latest accolades was an IM PR of 8:04:17 at IM Arizona. He retired in 2021 with his last race being Ironman Des Moines 70.3 in his hometown.
