I’ve created a Custom Ink Group order… starting Aug 10 thru Sept 22nd tell your teammates and get yourself some STG Swag !!
https://www.customink.com/g/ayt0-00cz-g1sz
This is similar to our Zoot store but for Hoodies (unisex), T-shirts and Tech T-shirts (men’s and women’s).
Custom Ink will collect your payment, add a $0.49 per item credit card fee, applicable sales taxes and shipping (if you want it shipped directly to you) free shipping means it comes to me and we will need to coordinate getting it to you.
We need to order at minimum 40 pieces total to make this a reality.

- 🏊 SLOWS 🏊 (Sammamish Lake Open Water Swim)Sammamish Landing, Sammamish, WA
Details
Join us for a Sammamish Lake Open Water Swim (SLOWS) evening swim! This event is for experienced open water swimmers ONLY!🕘 Start time: 5:30 PM check-in and get suited up, 6:00pm toes in the water.
📍 Location: We meet at the Sammamish Landing. 4607 East Lake Sammamish Parkway NE · Sammamish, WA.
⏱️ Duration: We'll stick around for an hour of swimming, but you don't have to swim that entire time - the time/distance you go is up to you!Equipment and Safety:
- A brightly colored swim cap and swim buoy are required for safety/visibility.
- In order to participate in any Seattle Triathlon Group event, you must sign our electronic waiver. Waivers only need to be signed once per year or if your contact info has changed. You can login to your account at https://www.seattletri.org/dashboard to check if you have a waiver completed. I will only be accepting electronic waivers - please complete the waiver ahead of time! No waiver, no swim!
- Our Open Water Swims (OWS) are non-lifeguarded, swim-at-your-own-risk events. As such, it is imperative that you be certain of your comfort level and ability to OWS. These are not designed for, nor should they be used for learning how to swim, or for inexperienced open water swimmers. An inexperienced OWS is a danger to themselves, and those around them. If you are not certain about your OWS capabilities, we suggest practicing at a lifeguarded swim beach or at a event designated for beginning open water swimming.
- There is NO guarantee of access to changing rooms/lockers, or gear watch on the beach.
- A swim buoy with a dry pouch is useful to bring your phone and keys with you on the swim.
- A wet suit is highly recommended. The wet suit is especially helpful early in the season but is not necessary.
