The Mailbox Sufferparty started as an idea to hike or run up and down Mailbox Peak as many times as you could or wanted to in a day. Mailbox Peak is a 4000ft climb... the old trail is 2.5 miles long, rugged, steep, gnarly. The new trail is 5 miles long... a little smoother... but still it's 4000ft of climbing. Rinse, Repeat... over and over again.

Last year we showed up, and a bunch of us ran all day and all night... 

Three of us did more than 7 laps, enough to "Everest"... Tyler did the most laps at 8! It took him 21 hours. Brad and Westy did 7.5 laps each. They were both out there for more than 25 hours. Lots of others just showed up and had fun... actually, we all had fun. Some people got pineapples for prizes for the fun they had. Because... Pineapples!

This year, let's make it a 24, 36, or 48 hour thing... just to see how far we can go. Let's have more people show up... to see how far they can go. Come join us in 2019, see how far you can go. You might get a pineapple!
