xXx Racing Relay Cross

2019 Relay Cross: Sunday, August 25, 2019 - Jackson Park, Chicago

Since 2010 this event has been a popular and fun way to kick off the cyclocross season. After a Le Mans start, teams of two riders alternate laps on a traditional cyclocross course. At the end of each lap, riders high-five their waiting partners, who leap into action to contest the next lap. Fields are available for men, women and juniors as well as the popular co-ed category.

New Venue for 2018!

RelayCX is moving! After many great years at Jackson Park we felt it was time for a change, and so our race has a new home: Warren Park. On Chicago’s North Side, Warren Park offers lots of free parking, nearby food options, and a sledding hill!

Returning for 2018

xXx Racing-Athletico is dedicated to supporting bike racing in and around Chicago by hosting races and supporting other organizations that help to build and maintain the amazing cycling and racing communities in our area. This year, we are again raising funds to help further this mission with the Relay Roulette race.

For this race, riders must be pre-registered, but will only find out who their teammate is on race day. The reg fee will be $5/rider, and all proceeds will be donated to a local cycling-related charity. The winning team will get to decide which charity gets the prize. We have a field limit of 50 teams for this race, which means if it fills up, there will be at least $500 to donate to a worthy cause! Every $5 you donate above the registration fee will not only get included in the donation, but will get you one entry to win awesome prizes. We’ve raffled off some amazing prizes in the past, and this year is no different...we’ve got 2 BLACKHAWKS TICKETS for one lucky winner! Remember, the more generous you are, the better your chance to win! ***100% of reg fees and donations from this race will go to charity***

As always, the juniors race will be free and will also be Co-ed! Brothers and sisters racing together in harmony!

Mark your calendars and follow us on Twitter, where we’ll announce the opening of registration. The 2018 version will take place Sunday, August 26 and the Co-Ed fields in particular always fill quickly.
