2026 11 14 Mud Slick Core Leoni
I don't have any information about an event called "Mud Slick Core Leoni" on November 14, 2026 — this doesn't match anything in my knowledge, and the date is in the future relative to my training data, so I can't provide an accurate summary. If you can share more context (e.g., where you encountered this, what "Mud Slick Core" or "Leoni" refers to — a race, a place, an organization?), I'd be happy
