​

​​Please note: You can come to either packet pick-up and do not need to let us know which pre-race packet pick-up you're attending.  If you did not sign-up for the $10 race day pick-up and can not make the pre-race packet pick-ups, just send an e-mail to Lance@withoutlimits.com letting us know you'd like to pick-up race morning, bring $10 cash with you, and plan on arriving 10min earlier than normal.

 

Race Day Pick-Up:  When you register you'll be given the option to pick-up your packet race morning for $10.  Why the fee?  While we don't want to charge any extra, it serves more as a deterrent so we don't have a 550 person line race morning. This packet pickup "convenience" fee is used to cover the cost in staffing the additional trained personnel needed to facilitate this extra special service.  Adding it to online registration also allows us to know what kind of numbers to expect race morning.  We love having athletes from Colorado Springs, the mountains, and Wyoming, and hate making you take a special trip on Fri/Sat.  The gas alone is probably $10. 

 

USA TRIATHLON ANNUAL MEMBERS: If you're an annual USA TRIATHLON Member you must bring your valid USA Triathlon card and a valid photo ID with you to packet pick up!  

 

NON-USA TRIATHLON MEMBERS: If you're not a USA TRIATHLON Member, then you already purchased the 1-day ($15) license when you registered and you're all set.  If you did a print and mail registration and forgot the $15, we have it in our records and you'll be able to pay the fee at packet pick-up. Please remember a valid photo ID.  As per USA TRIATHLON rules, you must pick up your packet as we're not allowed to release it to friends, husbands, wives, or relatives.
