The course runs almost entirely on grass through Expo Park, with gentle rolls underfoot and a few spots where the ground gets uneven. There is a small creek crossing and hay bale jumps along the way, which gives it the feel of a proper cross country course rather than a road race dressed up in trail clothes.

The Expo Park XC Runs has been held every year since at least 2022. That is as far back as RunSignup's records for this race go, so it may well be older.

Almost certainly not. Half the 3K field finished slower than 16:26, and the last recorded finisher came in around 21:41, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
It is a small race (22 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 3K, that spread matters more than the winner's time.
The 3K winner ran 13:42 while the median finisher took 16:26. That spread points to a relatively quick field, so expect a competitive front end.
