Details for the richest-ever World 100 were revealed Monday night by Eldora Speedway with more than $675,000 in cash payouts for the $100,000-to-win event.

The 56th annual World 100 set for Sept. 10-12 at the Tony Stewart-owned oval in Rossburg, Ohio, brings purse upgrades for every position including a race-high $5,600 to every starter, $1,000-to-start in consolation races and the expanded $3,000-to-win Coltman Farms-sponsored rookie program that pays back 12 positions.

Two preliminary nights are headlined by twin 25-lap semifeatures each night that set the starting lineups for the finale’s heat races that precede the 100-lap main event.

Additionally, the Coltman Elite Double Crown award will be presented to the best performer between Eldora's Dream and World 100 weekends. The winning driver will receive a brand-new custom engraved Rolex watch.
