Super Client spotlight on Masha Glanville

Super Client spotlight on Masha Glanville

Masha started adventure racing in the 90s because she loved the team based, non-stop adventure aspect of this multi-disciplinary sport. It was a way to see nature at its best all over the world and to push her limits. She raced in over 40 multi-day races (most were 10 day races) with her team mates all over Canada, the US, Patagonia, Australia and Tasmania. Within the last 7 years Masha started running more ultra running races which are 5 plus day long runs and have included Namibia, Costa Rica, Ireland and Reunion Island.

The ability to interact so intimately with nature in very remote areas of the world, while bonding with great people and animals is the primary driver for the love of this extreme sport.

To Our Beloved Community,

We are beyond grateful for your love and support during this unprecedented world health crisis. The outpour of your thoughtful messages for CORE40 are truly astounding, and we are incredibly thankful to play a part in your journey. 

We received an update from the San Francisco Health Officials, which informed us that fitness studios are anticipated to open mid August. We are committed to doing everything we can as an organization to continue supporting our community with virtual content during the shutdown, and we need your help to ensure we can reopen our doors for you when the time comes.

Due to many of your ample requests to support CORE40, and in light of the shelter-in-place extension, we are moving our live streams to our class schedule, which will need a “virtual class” purchase of $20 for registration in each live-stream.

You can expect Lagree-inspired at-home workouts led by our awesome team of CORE40 SuperTrainers. All the information you need regarding future live streams can be found here:

For those of you who are not in a position to support at this time, you can still view our past streams on the CORE40 IGTV, YouTube, and Facebook pages.

And remember, together we rise. 

With love,

Team CORE40
