If you haven’t yet registered for this year’s Philadelphia Marathon or Half Marathon, you’re out of luck. Organizers say both events have already sold out.

This is the earliest the races have sold out since the marathon weekend first started more than 30 years ago.

However, there is still a chance to compete in something this year. Spots are still open for the 8K race.

The events take place from Nov. 21 to 23. Approximately 37,000 participants are expected to attend.
