Yes, the Green Rock Orienteering Master (GROM) is back but has taken new form. Armed with an updated (Fall 2025) orienteering map by cartographer Jon Torrence, that will include a tract to the West of Scenic Loop Dr., and inspired by Gary Thompson’s upcoming seventh edition of the Tame the Dragon on February 28, 2026, we introduce the Green Dragon.

This “rogaine” style event will borrow the scoring system from previous Tame the Dragon meets. In a Score-O format, there will be 18 controls on the course. You will earn between 10-60 points for each control and also earn bonus points for completing sets of similarly valued controls. This format creates a unique strategic blend of endurance and planning as competitors seek to maximize the 4-hour window allotted to them. For visual learners, see table below.

For those who have been hesitant to head to Lake the Ozarks and commit to a full 8-hour rogaine, this one is right here in St. Louis and only half the time. Beginners are always welcome and will have the chance to go out and obtain controls at their skill level with the knowledge that you are right here in St. Louis County with good cell reception and all within the well-marked Greensfelder Park if you get a bit turned around. Take as much time out there as you like (course closes at 2pm).

For the mid-pack racers, the strategy of the meet opens up an opportunity to level up in the standings if you can plan and execute a strong route. And of course, for our most competitive folks…, well, expect me to run you up and down some hills and find as many parallel errors to bait you as I can. You’ll need all 4 hours to attempt the sweep.

Divisions: Solos and teams are welcome as seperate divisions. Based on registration, we will open up juniors (under 18), family (mix under/over 18), and masters (over 55) divisions.
