WED NIGHT! Week 6... 1/3 of the series in the books already.

Have you pre-registered? Please do.

We are under gunned at the computers tonight so please help us help you and pre-register before arriving. If you have a Timing Chip and Bib you're good to go BUT! Double Check your Bib and Chip ID online if you are unsure. Confirmation list is here:

Course is long... and using both the North and South fence line trails. Jump options and rock garden are back in play as well. Start goes up the long paved drag to the top of the stairs. Kids course goes left and merges off the road.

On a sobering note -
Isaac "Izzy" Sederbaum, who frequents Wed Nights, survived a Cougar mauling last weekend outside of N Bend. His friend SJ Brooks was killed. Izzy is currently in the Hospitol recovering from his injuries. This horrific tragedy rocked many within our cycling community. Our deepest condolences to the Brooks family. Out of respect for Izzy's privacy we won't be making a formal announcement outside of this. We will have a donation jar on our tables along with a GoFundMe account set up in support. If you have any questions feel free to speak with us. Thank you for your support during this terribly disturbing time.

Oh and Happy Birthday to Delia Massey, Julie Zivin, Jason Dougherty, Brian Marr, True Erbeck and little Quinalt Gramenz!
