This is another GREAT tip.
My long course tri bike leg screen has 3s Avg Power, NP, and distance, and that’s it. I turn all of my other screens off. You can set a watch for fueling, or if you know roughly when you’ll hit certain mile/km markers, you can fuel by distance. I actually did that during one relatively flat 70.3 and it worked really well.
For me, taking the results (time and speed) out of it really helps me make sure I’m sticking to my race plan.
