Friday's brick

I really wanted to go further but I had some time restraints even though I took the day off work. Bike 2:53:12 56.4 miles HR 137 19.5 mph, this pace is just over my target IM pace of 19 mph with some stoplights and some hills, just about no wind, partly cloudy day. 75 degrees, just about perfect biking weather. Gear selection was mostly 55/17 with 55/19 for the little uphills, cadence was mostly around 87 which seems to work really well for me. Run 1:37:30 10 miles ave HR 152, a bit high at the end near 156, probably a little light on fluids. Legs kind of tired too, the last couple of days has seen some volume. Nutrition for today was 6 gells, 1 cliff bar, 1 24 oz double strength orange Accelerade, 30 oz of water for the bike, transition was 20 oz of gatorade, run was 28 oz of gatorade (4 bottle fuel belt) and 2 gells, taken at miles 4 and 8, 1600 calories, could have done 1 more gell but I want to know what I can get away with. I know I can handle 1 gell every 2 miles if I had to.
