This is it – the SISU IRON. Team SISU members, this is the one event every year you will not want to miss!
We will not be telling you exactly what is planned for the event. What you can plan on is to be challenged like you never have before.
We have an amazing location reserved for this event – Camp Trask in Monrovia Canyon Park. It's a Boy Scout camp that has been used in several movies. There are snakes and bears…we will truly be escaping the city and entering the wilderness of the Angeles Forest. It's a beautiful setting with creeks and waterfalls. You can bring your tents and camp out before / after the event.*
We are also proud to announce that the SISU Iron is a qualifier for the OCR 24 Hour Enduro Championships!!! Top 3 Men and Women Qualify!
