Richtrova utilizes Martinez’s FreeSpeed Lab periodically to fine tune her position, rides often on Zwift, but still relies primarily on outdoor rides.

Richtrova has now ridden the same Quintana Roo PR Six frame for her 2019 and 2021 IRONMAN North American Championship overall female age group wins as well as her 2019 IRONMAN World Championship female 35-39 female age group title.

A few upgrades Richtrova made this past off-season included adding her Drag2Zero Ergo high rise extensions and a swap out of her mechanical shifting for Ultegra Di2.

While finding an aerodynamic position is important for Richtrova and Martinez, even down to Velotoze toe covers, Castelli aero socks and Castelli Tri Speed suit, they study each course to gain a better understanding of when it makes better sense to ride on the base bars and factor that into her overall CDA averages.

Richtrova uses the Giro Aerohead with the visor down but if she needs more ventilation from time to time the magnets keep it secured.

Richtrova’s base bar of choice is the Zipp Vuka 38cm base bar.

This side view reveals TriRig Omega One front brake and an XLAB cage which Richtrova used with a Torpedo bottle on race day.

Richtrova keeps a close eye on her power output using Powertap P2 pedals and also seen is the Alden Crank aero cover used.

Richtrova used an Irwin Aon 60/88 wheel set up with a rear WheelBuilder disc cover. She also uses a Dura Ace chain with Silca Chain blend.

A Cobb JOF Fifty-Five saddle kept Richtrova comfortable for five hours in Tulsa and during many hundreds of hours during training.

Earlier in the week Richtrova explained how vital nutrition is in long distance racing and Sunday she executed a new race fueling strategy developed with Martinez through metabolic testing and using PowerBar products that made a comeback at the end of 2019. She stored those PowerBar drinks in her XLAB Gorilla XT cages.

Earlier in the week Martinez and Richtrova let us see the Best Bike Splits estimation which calculated a 4:55:48 bike split. With the exception of a blunder coming out of T1 in which Richtrova had trouble clipping into her pedal, her 5:00:38 split was quite close to the calculation.

Looked like it was a challenging day out there in the Tulsa countryside.
