Not surprised, understand, but, super disappointed. Thank you for the up-date, and trust that your community will bounce back economically. Rooting and running for next year's event!

Thank you for the update! I was so looking forward to running this race in Mammoth, and still hope to do so in the future when it’s safe. In the meantime, I appreciate the virtual option!

Totally understandable considering the situation. Thanks for the very generous race decision plan.. way to go!!👏💪❤️look forward to better days ahead!! 🙏

Sorry this year didn’t happen. Definitely looking forward to next year. Definitely also understand Mammoths position on this too. Unfortunately there is no way they could handle it if it all of a sudden became a “hot” spot

I completely understand but am disappointed at the same time. You put on a great race on a beautiful course and I hope you will be back next year. Thank you for the generous options to choose from. ❤️Mammoth.

Heartbreaking to hear the town is struggling. I always look forward to visiting and hope we can be back next year.

Ran the course this morning! A little windy but absolutely beautiful!!

Disappointing, but understandable. Thank you for updating! ♥️🏃🏼‍♀️

Figured and totally understand. Hopefully Mammoth will open to visitors this summer sometime and we can visit and run the course.

Totally understand! If I come up and run the route on my own, can I pick up my bib and metal before?

As a lifelong local,we will truly miss all of you!!!!!

Safety first thank you, we will come back next year 🙏🏼

I’m in for next year... there I said it 🙂

Thank you for the Update. This is one of the most beautiful races I do every year. Hoping this nightmare is over soon and we can prepare for next year’s spectacular race.

Sadness 😞 see ya next year 😉👍🏼

Understandable for sure, but so disappointed! 😩😢🏃‍♀️

Where do we post our times?

Bummer!! ☹️

Booo

When will the goodie bag, finisher, and challenge medals be mailed?

Just wondering are we going to get a follow up email confirmation for the virtual race or are we just going to run it on our own and document it on own?
