Final Race instructions:

The Mega Fat Ass is all ready to go this Saturday January 22, 2022 at 8:00am.

Here are a few things to prepare for this weekend’s race:

If you haven’t already done so…take the time to go online and purchase a Discover pass. This may be for the person’s car (with individual license plate) you may be carpooling with…HINT HINT!! The
Discover Pass is REQUIRED for parking in Capitol Forest for the Mega Fat Ass or the Capitol Peak 50 mile/25k in April. The DNR enforcement office WILL be writing tickets! So if you are planning to run either of these races or any other races that are on Washington state land (including WA state parks), you might as well purchase an Annual Pass.

Everyone also needs to have a DNR waiver signed before checking in at the start. You can download and print out your copy here:

MegaFatAss DNR Waiver form

Printing these forms and bringing them already signed at registration will help speed up registration! This DNR waiver is NOT part of the online registration!

We will be giving out bib numbers before the start. Even if you already registered, please come early (prior to 7:30am) and you will receive a bib number upon a receiving your signed DNR waiver.

If you are not familiar with the Capitol Forest trails, print out the Course Map to take with you so you don’t get lost. The course is well marked with red/yellow flagging or orange spray paint arrows to follow the MegaFatAss course.
