Yet again we call all solar racers to challenge Helios in the ultimate competition to see who reigns supreme.
In 2026 Fabi has chosen the Missions 300k as the course on which we will race against Helios to see who will finish before the sun god on his chariot completes his journey across the sky and finish at western edge of our horizon at 19:59 (7:59pm). Be forewarned that sometimes Helios will conspire with Notos, the god of the south wind, to delay you in your quest to defeat the chariot driving deity.
Along the route you will stop by 3 missions in Southern California, this time actually visiting Mission Basilica San Diego, Mother of the Missions, which was skipped on the Missions 600k the month before.

Whilst the challenge is on, you may make the wiser choice by enjoying a journey through San Diego and Orange Counties on what will be a fun ride with friends exploring new roads on the longest day of the year!
Start and finish will be at Coronado Brewing in Knoxville where we will gather after the brevet to celebrate with drinks and food.
Please read our accepted proof of passage.
