Looks like you gotta lose 1.7lbs weekly. That is a bit tough for non-fat people, but doable. First 2 weeks you will obviously lose some water weight and still feel fairly strong, but the danger is that you might be a bit weak by the end of your cut.
This is why athletes usually prefer to cut a few lbs, even very little, like ~5lbs 24 hours before weigh-ins.
Because if you dieted for 7 weeks it places 7 weeks worth of toll on your body, no matter how you slice it, after dieting for 7 weeks you will be 7-weeks catabolic. It takes a while to get back all your strength and hormonal levels. So perhaps you may consider a compromise where you would drop a little bit now, and then a little bit before weight-ins. Another idea that comes to mind is to drop 2 lbs weekly for 6 weeks, and then bump up the calories a little bit last week so that you would take a break from dieting, and regain some strength.
During caloric deficit activity such as training should go DOWN in volume, not up. Because your recovery is compromised. For example, on a bulk many experienced people lift 4x per week, but on a cut 3x. And they reduce number of sets per workout, sometimes by 66%
So, watch out for over-training. If you're losing strength on a cut (usually happens after about 4-5 weeks, first 1-2 weeks you might even get stronger) it means you should cut back on volume and cardio (aka increase recovery)
We can't spike metabolism by eating more often, that myth has long been put to rest. But if you prefer you can eat more often, or if you do more than one training session per day, then you may want something to eat in between your sessions, for better recovery of course.
I recommend obviously that you count daily calories, and keep protein minimum at 1g/lb and fat at minimum 0.4g/lb, fill the rest of daily calories with whatever you want, but active individuals tend to do better with more carbs. Listen to your body, if you're craving fatty foods (olive oil, butter, cheese, hotdogs, burgers) your body may be telling you that it likes more fat. And if you find yourself drained in the gym, flat looking and craving sugar (bread, candy, cake, honey, fruit) your body is telling you you may need more carbs.
Finally for a serious athlete like yourself some supplements can help stimulate you and help your body burn fat faster. You should VERY carefully check what is allowed (if there is testing), but here are fat burning supps that DO work and have been proven to work in peer reviewed trials on athletes:

If you got no equipment, you can also do single leg squats, one arm push-ups, box jumps, planks, glute ham raise, and shoulder press upside down (feet against wall), be careful with this exercise! And with single leg squats, make sure to warm up well and not ever feel anything funny in the knees, start slow if you haven't done this before, start by holding on to something, or sitting back in a chair or a couch etc.
Check out Lyle's 3-part series on fat loss for athletes, this is famous stuff:http://www.bodyrecomposition.com/fat-loss/fat-loss-for-athletes-part-1.html
Lyle is a bit biased towards high protein intake, but he is still probably the best at this whole fat loss and performance stuff.
