1.5 Kilometer (.9-mile) Swim

The first leg of the Auburn Triathlon, the swim, lies in a secluded cove near the eastern edge of Folsom Lake at Rattlesnake Bar State Park. Rattlesnake Bar State Park is located 7 miles downhill from the American River Canyon Overlook (T2 and finish line), at the very rear extended ‘finger’ of Folsom Lake where the American River feeds into the lake, furthest away from the Dam and Folsom Lake proper. You will swim in a small bay surrounded by steep canyon walls and natural beauty. Swimming one big loop in clean water that began as snow in the high Sierra and flowed into the North Fork of the American River.  This intimate venue has narrow shorelines surrounded by high canyon walls and as a result always calm water which will hopefully lead to a wind sheltered early morning swim.  You will be only seconds from a shoreline at all times and attended to at all times by a team of kayakers, paddle boarders and rescue boats in the water. You must wear your brightly colored swim cap throughout the swim to assist with your safety. The water temperatures can be brisk, but the clear water most likely will be in the mid 60s. The last couple years the water temperature has been 63-72. Wetsuits may be mandatory depending on the temperature. Please see the Auburn Triathlon Swim Page for important information on Swimmer’s safety, prevention of swim related issues and how to prepare for a cold water start.

This is a safe course taking place mostly on rural roads with minimal traffic and only four signal lights in each direction which will be monitored by CHP or Auburn PD. Less experienced riders can feel comfortable that despite the hilly terrain, there are no dangerous descents or sketchy cornering. Please be prepared with proper gearing and fitness to climb steeply on Shirland Tract Rd from mile 3.5 to 4.5. Familiarize yourself with the route using all the resources on the website.

Detailed Descri ption

Exit transition area at Rattlesnake Bar boat launch parking lot onto windy park road heading to park exit gate. Right at stop sign to exit park on paved road. Begin a steady climb on Rattlesnake Rd heading towards Auburn. Stay Right at traffic island (mile 1.7) to remain on Rattlesnake Rd, following Auburn arrow on sign.

Continue gentle climb and arrive at “Scotty’s Corner” Feed Store and turn sharply Right onto Shirland Tract Rd (mile 3.3). Busy Auburn-Folsom Rd is just beyond your turn at this 3-way corner. Quickly, you reach one mile of the steep “Shirland Switchbacks” and awesome views of Folsom Lake and Sacramento Valley before a brief roller coaster section and a final gradual push to Maidu Dr in Auburn. Once you summit on Shirland Tract, descend quickly and then turn Left onto Maidu Dr. at mile 6 (departure from course of previous years). Turn Right onto Auburn-Folsom Rd, then Right again at Pacific Ave signal light. Caution steep descent then thru Sacramento St signal. Pass by American River Canyon Overlook-T2/Finish line at mile 7, cross a bridge over the run course, and continue to the narrow Gum Lane (just before railroad tracks).

Turn Right onto the narrow Gum Lane. Proceed past Maki Heating and Air building (blow them a kiss, they gave permission for the race to pass thru their private road and for the city to pave the road), banking hard right into the rear parking lot. Proceed through the rear parking lot (very rough pavement) and head up the newly magnificently paved lane/bike trail, then quickly down to Belmont St and turn Left. Then Left on Belmont St, quickly Right onto Gold St, then quickly Left onto Virginia St. Follow the 90 degree turn then climb a short steep hill to the T-junction at Brook St. Left on Brook (only choice) and immediately stay left at the traffic island. Caution: Yield cars at traffic island.

Follow the double yellow line of the most prominent Brook St through a few cross streets and a soft bank to the left, where name of road changes to Marvin Way. Proceed on Marvin to the 4-way intersection and turn Right onto Borland St. Proceed on Borland St past businesses and through the Auburn PD-controlled intersection of Highway 49.

Name changes to Lincoln Way as you begin a substantial 2-mile climb to the east end of Auburn and the busy intersection of Foresthill Rd. Proceed Straight through CHP-controlled intersection, past Raley’s shopping center and other businesses.

From here go for a few miles on the freeway frontage rd. Turn Left at Bowman Under crossing Rd (SS), crossing under I-80, then immediately Right on Bowman Rd. Follow Bowman Rd freeway frontage, descend briefly and approach the signal intersection of Bell Rd. Proceed straight through CHP-controlled intersection at Bell Rd as you follow the I-80 closely. Soon you will encounter a brief climb to AID Station #1 at mile 12.7. Next is a fast, steep descent down “LeMond Walked Hill.” Turn Right at the stop sign at the bottom onto Dry Creek Rd. Follow Dry Creek as the road changes name to Lake Arthur Rd, continuing along I-80 frontage. Pass the tiny Lake Arthur and then turn Right at Placer Hills Rd, crossing over I-80. Turn Left onto Applegate Rd and follow this freeway frontage road along the South side of I-80. Climb gently to the turnaround point on Applegate Rd to just before Cheryl Lane at mile 15.7 about 1/2 mile beyond the Applegate Rd turn after crossing freeway. Elevation peak ~1,660′. Return on Applegate Rd to Placer Hills Rd (turning Right and crossing over I-80). Turn left onto Lake Arthur Rd, CHP is controlling this signal intersection. It is here that those doing the World’s Toughest Half turn right for their out and back section you go left on Lake Arthur frontage road.

On the return route, you lose elevation all the way back to Auburn, except for a major climb back to the top of Bowman Rd (aid station location). Here you will begin a punishing climb of .4-mile at 12% grade. Greg LeMond once walked this climb in one of his many training sessions in the area. This is a fact because it was spray painted on the road at the base of the climb.

Reach the top of the climb and encounter AID Station #4. Descend quickly to the signal intersection at Bell Rd (CHP control) and proceed straight through with extreme caution. Continue along Bowman Rd freeway frontage, tackling a small climb before basically smooth sailing to the finish line ~300′ below you and four miles away. Turn Left at Bowman Under crossing, under I-80 and then quickly Right on Lincoln Way. Proceed with caution for as you enter the business district of Auburn. After .4-mile, proceed through the crowded intersection at Foresthill Rd (CHP control). As you leave the fast food cluster and get a little breathing room, you will commence a fast descent along the Lincoln Way freeway frontage.

Proceed straight on Lincoln Way up one last short climb. At the top you will proceed on flat road briefly before facing a steep descent approaching the signal intersection of Highway 49. Proceed straight through the Auburn PD-controlled Hwy 49 intersection and continue as the road changes to Borland St. Please use extreme caution on this steep descent approaching a busy intersection. Use common sense and watch for cars that may not be obeying police commands.

At the 4-way stop sign, turn left onto Marvin Way. This is a tricky intersection with three roads branching off of it. You are following the choice furthest to the left – look for the double yellow line and follow that as well as the Auburn Bicycle Trail Signs. Follow Marvin Way as it quickly banks right and turns into Brook St. When in doubt follow the yellow line or the most prominent road. There are a couple curves where another road branches off and its not always well signed. Stay right at the Y island intersection of Brook St and Robie, climbing a steep 50 meter bump to a forced 90-degree bank at end of Brook onto Virginia St.

Descend steeply on Virginia St (caution), then follow another 90-degree bank. Then proceed to Gold St stop sign and turn Right. Proceed on Gold for 300 meters to Belmont and turn Left (before train tracks). Proceed 100 meters uphill on Belmont to narrow, unmarked Gum Lane and turn Right on Gum Lane. Enjoy this newly paved bike trail/Auburn Tri race course and thank the City of Auburn public works dept! There is NO PASSING on Gum Lane from Belmont to Pacific Ave – just take it easy and proceed with care. Try to pass and you will be penalized 15 minutes and fined $20! Using Gum Lane allows us to use quiet back neighborhood streets, avoid all major Auburn intersections and avoid a possible train crossing ruining your bike split. Thanks to Maki Heating and Air for letting us use this private road where their business is located!

You will climb steeply and then the road banks 90 degrees left at the top. Be especially careful to get through Gum Lane carefully. Follow the narrow and now paved Gum Lane as it winds through industrial offices (bad pavement in parking lot), crosses over a canal on a narrow bridge and reaches Pacific Ave. Turn Left on Pacific Ave and proceed for 200 meters uphill and turn left into the transition area at the American River Canyon Overlook to complete ride.

10K (6.2-mile) Run

The 10k run is on a spectator-friendly course – a scenic and challenging route through the Auburn State Park and Auburn canyon-edge neighborhoods. Enjoy the tranquility of a course primarily closed to auto traffic and affording stunning views of the American River Canyon at seemingly every turn. The Auburn International run course is consists of two laps, the first lap is 3.5 miles and the second lap 2.6 miles which is the Mini loop.

International Run Course Detailed Description

The run starts right out of T2/Finish on the same course as the Half and Mini towards the Western States Trail. Within 300 yards heading downhill you will come to an intersection where the Half triathletes go straight and the International and Mini turn RIGHT. There will be signs and a volunteer directing you. This trail contours below T2 where you will come to a paved road (Pleasant Ave closed to traffic) and turn LEFT. Continue down to a 3-way intersection where you will bear LEFT heading down hill. The Mini athletes will go straight (your second loop you will go straight here). This section is also part of the Worlds Toughest Half run course where runners will be merging. This portion is an out at back. Please stay on the left side of the road in this direction. Continue down to your first aid station at mile 1.5. This is the turn around point for the International but the Half runners will continue so do not necessarily follow the runner in front of you.  Front runners made this mistake 2 yrs ago.  Continue back up hill again staying on the left side in the direction of travel. You will come back to that 3 -way intersection where you will now turn LEFT back onto Pleasant dr back onto the Mini course. Proceed to mile 2.5 and aid station. Just beyond the aid station you will turn RIGHT onto Maidu Drive. In approximately 75 yards take another RIGHT onto the Shirland Canal dirt trail. This section is flat and offers shade. Continue to mile 3.2 where you will be directed to turn RIGHT by signs or a volunteer down a slight hill and crossing the paved road (Pleasant Ave closed to traffic) and onto a trail followed by a gravel double track and up a short hill that leads  up to  Pacific Ave where you will go RIGHT. In approximately 100 yards turn RIGHT into the American River Canyon Overlook, T2, where you will run thru a cheering spectator lined chute and then will continue on for your second loop, (2.6 miles, the Mini run course) retracing your steps to that 3-way intersection on the paved road. At this intersection this time proceed STRAIGHT following the Mini course to the same aid station you passed at mile 2.5, which is now mile 4.9. Again just beyond the aid station turn RIGHT onto Maidu Drive and RIGHT onto the Shirland Canal trail back to the finish as before.
