I have done a few half irons, actually two and have only done two tris in my life.
I sold extra broadheads, shafts, extra handgun mags, hunting packs, etc to get a BW. I lost a ton of money in the depreciation of my compound, but ended up way ahead with what I got in return.
Races are very expensive for sure, I am skipping this tri season for financial sake too. I may do a marathon in June if I can commit the wife to that being a family vacation, but otherwise trail running is how I am getting ready for hunting season.
One half iron and the cost to get there and back, plus a month of supplements and such are about what a BW is...
