Training for Marin Ultra Challenge 50k 2025

This Saturday, I’ll be towing the line for the Marin Ultra Challenge 50k. First ultra this year, first time ever that I’m doing the same ultra for a second time and first time running as an Inside Trail Ambassador. We left things on this blog at my SF half training. Well, the race went really well, more details on my Strava post. In this post, I want to detail my training for MUC, starting after my Javelina DNF and my race mindset for this Saturday! ...

Preparation for the 2025 San Francisco Half Marathon

My first race for 2025 is coming up, the San Francisco half marathon on Sunday, February 2nd.

I’m a little nervous going back to road racing, but training has showed I’m in good shape and I’m looking forward to a great race. That said, this is not a goal race for me.

I’m writing this about 2 weeks prior to the 2024 Canyons Endurance Run 100k. This will be my first 100k trail run, and I wanted to share of some of my race prep. I’m writing this as much for the community as I’m writing it to show myself I’m well prepared for the race. Let’s talk about: The race itself My physical training What I learned in tune-up 2 races to adjust my Canyons race plan My nutrition plan My goals and my fears. About Canyons Endurance Runs 100k Canyons is a trail running event held around Auburn, California, sharing parts of its course with the Western States course.
