The schedule
Prices step up. Early runners win.
These are all-in prices: RunSignup's processing fee is already in them, so nothing gets added at checkout. Register in the early bird window and the marathon costs $89 instead of the race-week $149.
| When you register | Marathon | Half |

| Early bird Through Nov 22 On sale now Opens Nov 8 | $89 | $79 |

Each window closes at 11:59 PM Eastern on its last day, so the early-bird price is there all the way through Nov 22. You can register right up to race morning (thanks, Leone Timing), but the hoodie size guarantee ends race week, and the price never steps back down.
$10 off for those who serve
After early bird ends: military (current and former), first responders, and front-line medical workers.
Refer friends, run free
Refer three friends with your personal link and get $15 back, repeatable until your entry is free.
The rules
No refunds, ever. But you have four good outs.
The first three are self-service on RunSignup until the late-August cutoff. Insurance has to be added when you register.
| Life happened… | Your option | Fee |
|---|---|---|
| Can't run this year | Defer to 2028; no extra cost when you re-register | $40 |
| A friend wants your bib | Transfer to another runner (never hand it over informally; unofficial swaps DQ both runners) | $10 |
| Wrong distance | Switch between Full and Half (Half→Full also pays the price difference) | $10 |
| You'd want a refund | Event insurance, bought with your entry. Covers illness, injury or a family emergency; claims are handled by FanShield, not by the race. What's covered | Varies |
The three self-service options: sign into RunSignup → Profile → Upcoming Events → Manage Registration. Walkthroughs: defer · transfer a bib · switch events.
Deferred from 2026?
Claiming your deferred entry
Your 2027 entry is already paid for. You don't register as a new runner, and you shouldn't. Claiming it costs nothing:
- 1
Watch your email. When 2027 registration opens, RunSignup sends a claim link to the email on your RunSignup account. That link applies your deferral automatically.
- 2
No email? Sign into RunSignup with the same account you registered with in 2026, go to Profile → Upcoming Events, and complete your deferred registration there. Using a different email address is the #1 reason deferrals "disappear."
- 3
Still can't make it? We'll roll your deferral to 2028 at no cost, but it isn't automatic and RunSignup's self-service tools won't do it: send us a note and ask. Once claimed, a deferral works like any other entry, so you can switch distances or transfer it as usual.
Snags? Send us a note with the name and email you registered under, and we'll straighten it out.
What happens on course is governed by the Rules of Competition.
