I like this side bet for you. Pulling 500 after putting in high mileage for months is super hard. Most I ever pulled was 435, and I was 220 lbs and probably couldn’t run a mile. Now that I’ve been running for a year, I’d probably have a tough time with 315. I think he’s looking at 3-4 months after race day minimum, which gives you 6-7 months to shave off a second.
