Besides actual military ruck marches, what kind of ruck marches/events have you participated in and what are your thoughts about the them?

I also did the BAA Tough Ruck in 2017. I thought the course was great and made it manageable for a wide variety of individuals to participate. There was a good mix of civilians, service members and veterans. I highly recommend it to anyone.

Two years ago I organized a team mostly consisting of members in my squad and did the 31 Miles for 31 Heroes that raises money/awareness to support the surviving families of the 31 lives lost in Extortion 17 and provides funds towards the treatment of TBI/PTSD. The ruck took place overnight and honestly was one of the toughest I've done (at least mile wise) but the best part was at sunrise we finished at the gravesite in Arlington commemorating the lives lost.

Used to do the Volks marches when I was in Germany. Those were a lot of fun, got to see how life was in the smaller communities away from base and meet some neat folks.
