Registration

A portion of all registration fees will go to Save Mount Diablo to fund land preservation and trails.

Entry Fees

There are three prices: early bird (before 3/11), regular (until 4/8) and late/race day entry (after 4/8). Those wishing to skip a shirt for this event may deduct $5.00 from their entry fee. We recommend saving money and entering early!

5K Entry Fee: $35 until 3/11, $40 until 4/8, $45 after 4/8

10K Entry Fee: $40 until 3/11, $45 until 4/8, $50 after 4/8

Half Marathon Entry Fee: $60 until 3/11, $65 until 4/8, $70 after 4/8

50K Entry Fee: $85 until 3/11, $95 until 4/8, $105 after 4/8 (Price includes shuttle to start, but must be registered by 4/8 to be guaranteed a seat.)

Please note: To be guaranteed your shirt size (or a technical shirt), you must register by April 8th! We will have plenty of extra shirts on race day, but it is always possible that we will run out of your size if we do not know what it is in advance!
