    Millerton Lake Triathlon, Duathlon, 5K & 10K

    Meadow Campground, Friant, CA 93626, USAView event
    About the event
    From the organiser

    The Millerton Lake Sprint Triathlon has long been known as a great "first lake swim" triathlon, and a warm up for the upcoming season. But don't let the bike and run distances fool you, there are a few steep hills on the ride, and the trail portion of run is a challenge.

    More of a good thing... The Olympic Distance has a more challenging swim, two loops of the bike course, and two loops of the run course with a trail run heading out, a paved road coming back and beautiful Millerton Lake as the backdrop.

    A USAT membership is required for the Triathlon, (but not the 5k) If you do not have one, you can purchase one during the registration process.Total participation at this event is capped at 250. Register before it is sold out.

The trail run is hilly with a mixture of paved paths, fire roads and single track trails.

      Loved it! I will definitely being doing it again this year. The bike killed me, but I plan to train harder on that. Unfortunately, my goggles broke right before the swim so I had to do backstroke. I will hopefully have better results next time.

    • Did the Sprint Triathlon in 2018

      Excellent! I won my age group for the third time in a row. The reason I rated the course just 'OK' is because the back road coming up the hill needs a serious repaving job. It's like riding the cobbles in the Tour de France. At least the cones were placed such that you could use the whole right lane to dodge all of the pot holes and cracks. Also, the transition area needs a repaving job as well or just a running mat between all of the bike racks. The turn-around point of the run was also one-tenth of a mile further than the last three years, for a total of .2 miles total further. No wonder my run time was much slower than the last two years. And it would be great to have a few more buoys to sight off of during the swim.
