I went way over. I had estimated $120 and ended up spending $203. Brunch was $30, my tri shorts were $55 (and then I treated myself to a $20 tri shirt). Groceries ended up being $30. Gas was $10. Post-race lunch was $20 and then debate beer and a box of hair dye was $18. Oh, and one of my recommendation letter writers told me I needed to sign up for a letter-delivery program to make her life easier, which was a $20 annual subscription.
I should not have bought the shirt and hair dye and post-race lunch. I just felt like treating myself post-triathlon. Womp womp.
