I'm A Tiny Bit Overweight, But I've Lost A Lot

I'm a tiny bit overweight, but I've lost a lot in the past few months. I have one of those "obstacle course fun" things that everyone is doing these days coming up in two months and I've started to ramp up training. I've never been for a physical before and never had any bad side effects from working out. Should I go for a physical to see if I'm fine before pushing myself like this.
Btw I'm 28 and 95kg and 171cm. My bmi says I'm tech obese but I think I only look "bigger".
