Travis from Repack Racing here - I am working on an endurance event to fill the TT100 hole as part of the California Dirt Endurance Series. The venue is Six Sigma Winery using their back country trails in development. I’m about 80% sure this is going to kick off. I’ll announce it right away on our IG channel instagram.com/repackracing or you can check the website repackracing.com

Does @Jonathan know anyone involved in TT100 to get the scoop on the demise of TT100? Permitting issues, financial challenges, fatigue of organizing a race for 10+ years? Essentially looking to understand if it’s likely someone else will fill the gap, or if the issues are universal (like Forest Service permits), and the gap will be around for a while.
Entered a 50k local race, and will enter some of the 20k local series races closer to each race when I know if I can make it or not on a particular weekend.
Thanks,
aka a very small group of people with enough money to buy a very large megaphone to make them seem like a bigger group that’s highly impacted by a one day race.
We seem to think cycling is expensive, being an equestrian is a level or ten above next level.

I am closer to the other end of the Tevis Cup / Western States course, and there’s been reports here and there of equestrians also trying to tell cyclists that they’re not allowed on the trail, even though the are (bikes aren’t allowed in the Granite Chiefs Wilderness and one other short bit at the end, but the vast majority of the WSER course is open to bikes).
@Repack_Racing if you end up wanting to put on a 2027 event at Tahoe, and need a letter writing campaign to get Forest Service permitting, just let us know 
Tahoe is really an amazing spot. And large lap xc and xcm type riding is a great way to enjoy it. And like many of these “crowded” places, once you’re 1/2 a mile from the road/trailhead, they’re very empty.
The Mammoth race looks like a great event, with 2x10 mile lap on the ski resort for most people and 3x10 mile for the expert.
I’d def be down for it. email me at travis@repackracing.com

Looks like there’s an event announced at Tahoe to replace TT100. Same weekend, different start/finish and different trail.
