New and old fans of its home on Paramount+, the show is timed perfectly with the release of old seasons of The Challenge available on various streaming platforms.

With ages ranging from their early 30s to over 50, fans have been curious as to exactly how old each of the competitors is. In addition, many have been absent from the public eye for a while, and fans are curious about what they've been up to. Viewers are wondering if age and the length of time since someone competed plays a role in their predicted success. For that reason, we've compiled a list of how old each Challenge: All Stars cast member is and how long it has been since they last saw a season of The Challenge.

Alton Williams

Alton Williams The Challenge All Stars

Age: 41

Last Challenge: 2012

Alton is one of the only Challenge players who has very little social media presence. Alton has not only disconnected from social media, but doesn't watch much TV and hasn't kept up on The Challenge over the years. His return to the show is one of the most anticipated by fans. His lack of info on what has transpired since he left makes the social aspect of the game a little more challenging for him. Without active social media, it has been hard for fans to keep up with Alton. He's tight-lipped about his personal life as well, after a long on-and-off relationship with his Real World castmate Irulan Wilson.

Jisela Delgado

Jisela Delgado The Challenge

Age: 40

Last Challenge : 2006

Jisela took a break from raising her beautiful sons to come back after a 15-year absence. Fans have been able to keep up with her via Twitter @JiselaDelgado and Instagram @withlovejisela. She is very active on social media and fans have seen she isn't afraid to get into some Challenge social media beef. Jisela has gone home fourth in every Challenge she has participated in, so it will be interesting to see if she is able to break that curse this time around.

Ace Amerson

Ace Amerson The Challenge

Age: 42

Last Challenge: 2007

Ace's return to The Challenge after 14 years didn't last long, as he was the first person eliminated. That's not quite in line with the success he has seen in the past. He posts occasionally on his Instagram, @aceamerson11. Though details about his personal life seem murky at best, he appears to be enjoying the country life and has mentioned a girlfriend as recently as late 2020.

Katie Cooley

Last Challenge: 2010

Despite once being a staple on The Challenge, Katie's life before All Stars was a far cry from what it was back in 2010. Katie, who works as a Senior Finance Manager for Wrigley Media Group, is happily married and has her hands full raising her 5-year-old daughter, Avery. However, she still makes time for her ion, interior design. You can check out her work on her blog, decorkate.com.

Derrick Kosinski

Derrick Kosinski in The Challenge

Age: 37

Last Challenge: 2017

Kosinski is someone even new Challenge fans will be familiar with. Having appeared as recently as 2017, he remains an all-time favorite of many, including host TJ Lavin. His podcast, Challenge Mania, which he hosts with comedian Scott Yager, is one of if not the best source for all things Challenge-related. Despite being busy with his podcast and his even more important role as a dad, Kosinski manages to stay very active on social media. He can be found on Instagram @derrickmtv and Twitter @DerrickMTV. Kosinski is also widely considered one of the most fierce competitors, but also one of the most likable players in the show's history.

Syrus Yarbrough

Syrus Yarbrough on The Challenge

Age: 49

Last Challenge: 2009

At almost 50, there's no doubt Syrus is one of the oldest people The Challenge, but he doesn't appear to have slowed down much over the years. He has been in movies and on TV, worked as a network consultant, and even dabbled in fashion, with some of his clothing available at his website, iamsyrus.com. The long-time bachelor appears to have settled down and has been reported to have a serious girlfriend as recently as 2020.

Beth Stolarczyk

Beth Stolarczyk in The Challenge

Age: 52

Last Challenge: 2008

At 52, Stolarczyk is the oldest competitor on The Challenge: All-Stars and the oldest to compete in the franchise, period. Fans of the show have noticed her age isn't slowing her down as much as one would expect. She got married 12 years ago and is a proud mom to two beautiful children. If that isn't enough, she is busy as the founder and CEO of Eyelushion Lashes in Beverly Hills. She can be found on Instagram @bethsrealworld and on Twitter @MTVBeth.

At 35, Nehemiah Clark is one of the younger of The Challenge: All Stars cast. Clark lives in Kansas City, Missouri where he remains close to his Real World costar, Challenge great Wes Bergmann. While his social media makes no mention of a significant other at the moment, he has been plenty busy in the 10 years since his last Challenge. He has worked as a DJ, hosted a weekly podcast, done some impressive work as a set designer/set dresser, as well as videography work as a director/editor.
