4MPH Challenge | Up to 12 miles, Up to 36 miles, Unlimited

March 23, 2019 @ 8:00 am - March 24, 2019 @ 5:00 pm


Start: Whiskeytown National Recreation Area- Oak Bottom Beach

Leg 2 Start: Camden House Parking Lot: 


Race Details:


Can you manage a 15 minute per mile pace on relatively benign trails?  Of course you can!  Most of you could do sub-10min/mile, many could do TWO miles in 15 minutes.

And in this race, that’s all you have to do!  15 minutes per mile.  4 MPH.

A fairly easy (one medium size hill) 6-mile point-to-point course from Oak Bottom to the historic Tower District (near the Camden House).  2.5 miles of lakeshore running and some great views at both ends of the course.  Mostly single track with a half-mile section of road in the middle.  Any time under 90 minutes counts as success! When you finish, you can sit down, eat and drink, visit with other runners, whatever.

When the 90 minutes are up, head back the same way to Oak Bottom.

Once again you have exactly 90 minutes to finish.  And then…

You Get To Do It Again!

The first time that you fail to finish a 6 mile leg in 90 minutes, game over..

And if you do make it, congratulations, you’re tied for first place!

How many legs can you do?  How many miles?

How long can you keep up a 4MPH pace?

Since everyone starts every lap together and hangs out together between laps, this is a very social event.  As for the race yourself, whether your goal is one lap or 20, your main competition is yourself.  How far can you go?  And will you be able to come back next year and go further?  No time limit, I’ll stick around as long as you keep up the 4MPH pace!  (I’m not worried, I know that sleep deprivation will catch up with you eventually).

Aid Station Info:

We will be providing aid stations at each end of the course (every 6 miles).  You will still want to bring a chair for each end if you are planning to run further than 12 miles.  We will provide basic aid station fare, you can bring drop bags for your personal dietary preferences.  We can fix something hot and simple for runners who are still competing after the sun goes down (every six miles until the finish).  We will have a microwave oven available beginning at sundown at Oak Bottom if you want to bring some microwaveable foods of your own for Saturday night or Sunday and beyond.

We will find you a ride back to the start if you have to drop at Tower.
