Tri-C Karters Endurance

Thanks to everyone who joined us for the Endurance Race at Adams last month with KPV and LO-206's racing late afternoon into evening. Delay in getting photos posted due to a lost camera charging cord.

Due to Covid-19 we were limited on numbers of teams (we ended up with 19), no spectators and very limited mechanics/parents.

The day started out ok and quickly went downhill with extensive timing loop issues. Once the loop was replaced, the event essentially had to start completely over.

Nevertheless, it was great to see everyone who turned out to race and we hope to all be back to regular racing as soon as we can.

REMINDER - Registration closes in 5 hours ... just a couple team spots left. There will be no on site registration.
