I'm on a push to drop body fat by June 25th, and would appreciate any TriFueler's tips.

Background:
Weight: 280lbs
Height: 6'8"
Body Fat: 25%
Age: <30

The testing method used is the caliper test.

Here's the plan:
Drink water (I have been doing about 3-4L/day plus 1L/day of caffeine free tea)
Run 3x per week (I have been doing this for a few weeks now, 3-5mi at a time)

Last June (like many other June's) I decided that I would start running, again. I'm only 5'7" and I let my weight get up to 190. Luckily, this time my June running fever kept going and I did about 6 road races last summer. Bothered by tipping 190 for the first time ever, I also signed up at the pool so I could swim during my lunch hour. Since I was already running and swimming, I bought a bike and did my first 2 triathlons. As a result of all this fun, I lost 15 lbs in 3 months.
