Result in 30 day challenge

So far, i have gotten a lot faster, but i have not done a 400IM yet.  i have improved in my 200IM by a whopping 12 seconds! if i was doing a 400, then i might've improved by almost 20 seconds. i felt really happy when i got my time for the 200IM, because i know that i'll improve on the 400 even more! i think i have reached my goal.and maybe even exceeded it. have any of you completed your goals?
