Been tracking marathon finish times lately, and it’s wild how much the stats can shift based on weather or runner form. One trick I’ve found is focusing on mid-tier runners—top dogs are too obvious, and the odds reflect that. Last race, I pegged a guy who’d been pacing steady all season, and he came in under by a solid 20 seconds. Paid out nice. Anyone else messing with these bets? Data’s your friend here.
