Jess Sims taught her first solo Peloton cycling class on October 22, 2026, subbing for Jenn Sherman at the last minute for a 30 min 70s Ride.
Jess shared on Instagram that Jenn got stuck in traffic, so she wouldn’t be able to teach her class. Jess was already teaching that morning, with a 30 min Full Body Strength class at 9:15am followed by a scheduled Flash 15. She still taught strength, but the Flash 15 was canceled so she could take over Jenn’s 10:00am ride. That left just 15 minutes to switch studios and get ready.
In the video with her post, Jess explained that members were already being brought into the cycling studio while she was still teaching strength. She thanked the team who helped her make the transition, describing Peloton as a team sport.
Jess has taught Bike Bootcamp since the format launched in 2020, and previously joined Robin Arzón for the Lizzo 2-for-1 ride in July 2022. The Lizzo ride was also a substitution, with Jess filling in for Cody Rigsby after he said he was under the weather. This time, she was leading a regular cycling class on her own.

Jess opened the class by welcoming 39 riders in the studio, and nearly began explaining where riders should put their mats:
“I can’t believe I’m not teaching a bike bootcamp. I was going to tell you about where to put your mat. You don’t need your mat.”
About halfway through, she joked, “Wow, not getting off the bike is fun. Who knew?”
Jess also kept Jenn’s original playlist, despite 70s music being outside her usual class playlist. In her caption, she said she initially thought about switching the music when she learned the theme. Then she saw Earth, Wind & Fire’s “September,” her dad’s favorite, and decided the playlist was meant to be.
During the ride, Jess used the song for a climb. She also said Jenn always checks in on her whenever she’s on the road, and called filling in for her “the ultimate honor.”
Near the end, Jess read a message from her producer: “proud of you, sobbing.” During the closing stretch, she shared a line she lives by:
“Something that I live by is being ready is not a feeling, it’s a decision.”
