They have their own web page which will explain it all to you
I've seen it advertised as 1/4 mile, and as 3/8. I'd say closer to 3/8, as I have raced at Merritt and 1/4 mile asphalt.
The track is a dirt track that's 1/4 mile. A ton of fun just don't sit in the bottom 5 rows in the stand especially at turn 4
3/8 of a mile
