I... got my kata tip

That means that the senseis think my performance of enpi kata is adequate to grade on. (You have to get three tips on your belt, for combinations, kata and semi-freestyle sparring, before you can grade.) I wasn't even going for any tips. I just did the course because it was compulsory for brown and black belts. At the start of the course, I didn't know all of enpi and I couldn't do the jump.

This course really brought home how much fitter and stronger I need to be, as a brown belt. Afterwards I was just exhausted. I sat on the floor, drank Lucozade and ate cake for twenty minutes until I had the energy to get up and get changed. (Much like after the Halesowen Aquathlon, where I spent twenty minutes sitting on the changing room floor, eating cake, rubbing moisturiser into my chapped belly, and staring into space.) In a year or less, I'm going to have to do that, plus a four-to-six hour grading afterwards. Oh god.

OKAY! Now I'm off to the gym.
