Sure. Appreciated the data you had on battery consumption of the phone as a bike computer. Using that, the OP should be able to decide how he wants to proceed. 200 miles is probably pushing it for a phone. Might be worth borrowing someone's bike computer for the ride.
Half the fun of these things is figuring out all those little logistical issues.
