Weight Loss - Acceptable Caloric Deficit?

Hello everone,
I have a question about loosing weight strategy. I am following ssbhv 1 plan and also want to loose 5 kg. So i use fitness pal and choose 0,5 kg loose per week. So i need to take about 1750 caloris per day. And also i need to fuel for hard workout as well. For example today i am going to do wright peak -2 (which is 3x30 mins 85%) and i will burn 1600 caloris approximately. So do you think i ate well for today? I ate 1.400 caloris surplus and 2 hours later i will do the workout and do not consume any caloris during and i will burn 1600 caloris. I ate too much but i will burn them i think. But i do not sure wherher it is true or no?

P.s: i am 79 kg with 1.88 cm height rider. (298 ftp)
