See all- 🚴 Double S.M.I.L.E. 🚴 (SATURDAY Mercer Island Loops for Everyone)Lid Park, Mercer Island, WA
This Saturday is looking nice again, let's go for a ride outside!
For this route, I'm going to do two "SMILES" - starting with Mercer Island, followed by the lower Lake Washington loop. This totals 33 miles, which is about 1.5x the normal SMILE out-and-back route. As this is an early-season ride focused partly on the great weather, we're doing this in the afternoon instead of the morning. I'm also capping attendance at 15 as I don't feel comfortable leading a bigger ride on the open roads there.
🕘 Start time: 1:30 PM
📍 Start location: Mercer Island Lid Parking Lot
⏱️ Estimated duration: ~2.5 hours
🌦️ Weather: rain will cancelRoute: I plan to ride the “Double Smile”, meaning I’ll start at the parking lot at the Lid Park on Mercer Island, ride south along W Mercer Way all the way to the south end of the island and back up E Mercer Way until reaching I-90, then cross I-90 eastbound and continue with the clockwise Lake Washington loop around Renton Airport, returning to Mercer Island via I-90 eastbound. Total distance is about 33 miles, 1250 ft of elevation. There is a restroom and water fountain nearby the start/finish, some options near the Landing in Renton, and again at Seaward Park.

Pace and regrouping: This is a drop ride with two planned regroup stops. You should expect the ride to split into smaller groups based on speed, and you could be riding portions solo. I'm very out-of-shape right now, so expect I'll maintain an average pace slower than last year (13-14 mph), which translates to about 16mph on the flats.
Equipment and Safety: Helmets are required to ride. A good headlight and taillight are recommended. Rain (however unlikely) will cancel this ride. Bring your own nutrition you expect to need during the ride. Riders should be able to sustain the appropriate pace, know how to read a cue sheet, change a flat tire (and have the requisite equipment to do so) and have a positive attitude. Ride Leaders and Sweeps will not stop long for flats or mechanical issues due to group safety.
In order to participate in any Seattle Triathlon Group event, you must sign our waiver. Waivers only need to be signed once per year or if your contact info has changed. As this is early season, if you participated in an event with us in 2024 you like still have an active waiver from last year - click the waiver link above and login and it will tell you if you already have a valid waiver. I will only be accepting electronic waivers - please complete the waiver ahead of time!
Thanks and Tri On!

📍 Location: We meet at the bench/cove just north of the lifeguard area on WEST Green Lake Beach (What3Words app = reef.puppy.handle).

- 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 calendar year or if your contact info has changed. As this is early season, if you participated in an event with us in 2024 you likely still have an active waiver from last year - you can login to your account at https://www.seattletri.org/dashboard to check. 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.
Please feel free to ask any questions in the comments.
Thanks and Tri On!
