The only resource that I know of is the Katy 50/50 Facebook page: https://www.facebook.com/katy5050/
And for everybody wondering "so WHAT IS the Katy Trail 50/50?"...
It's an ultramarathon (i.e. foot race, not bike) with distances of 50 miles or 50K (that's just over 31 miles for the metric-impaired). This year it's scheduled for September 4, 2021 at 6:30 AM, starting and ending at Marthasville. And as you would expect, a good portion of the route uses the Katy Trail.
