When I redid my feat list for my two Curse of Strahd games, I made sure to split it up into Non-Combat and Combat related feat lists (and there were various points when people would choose from one or the other.) I then combined many of the half-feats together to make larger and more useful versions for people. So Athlete was combined with Mobile to create the Freerunner feat:
FREERUNNER
- Your speed increases by 10 feet.
- You may use a Bonus action on your turn to take the Dash action.
- Difficult terrain doesn't cost you extra movement.
- When you are prone, standing up uses only 5 feet of your movement.
- Climbing doesn't halve your speed.
- You can make a running long or high jump after moving only 5 feet rather than 10.
- When falling, you may reduce the distance fallen by 20' for the purposes of calculating damage.
It was a much more attractive option for the PCs that cared about mobility.
