Thinking about doing a 58k (36 mile) trail ultra marathon next year, am i mad?

It's a great goal to have. My sister did something similar when she turned 40. She was over weight and never had run in her life, and made a 60k run her goal. You can do it too if you prepare properly. There's a ton of advice for it online. Good luck!

Sounds great. Trying new things. Great for you!

No way! That’s awesome! My
(step) mom & I did a 35 mile walk for breast cancer that was great. Go for it!!
