Mcallen, TX
This is a holiday-themed race held at Tres Lagos in McAllen, a lakeside development with paved paths and open space. The course is flat and the Grinchmas theme means you will likely see some festive costumes along the way. It benefits a local pregnancy resource center, so the crowd has a purpose behind it beyond just the run.

Going by the 2025 results, this is a decent-sized field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

The Grouch-Mas 5K has been held every year since at least 2024. That is as far back as RunSignup's records for this race go, so it may well be older.

How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Nov 12, 2026.
Set a goal and get a pace band: every mile split on a card sized for your phone lock screen, so race morning needs no math.

Almost certainly not. Half the 3.1 Miles field finished slower than 39:24, and the last recorded finisher came in around 1:14:29, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
A field of 548 is big enough that you will have company at your pace without feeling lost in a crowd. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 3.1 Miles, that spread matters more than the winner's time.
The 3.1 Miles winner ran 17:22 while the median finisher took 39:24. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
