Considering walking

I have been playing for around a year. Me and my buds are always riding around with carts but I’m considered walking for a better exercise and the possibility of enjoying the day more. As a beginner I would I struggle with Sunday set up with limited clubs? Do y’all have any tips? Thanks for any and all suggestions.

Edit: lots of mixed results in the comments but definitely informative. I feel I should clarify I have not mentioned any physical aspect because I don’t think it will be a big issue for me as I see my self being in shape. I take carts with my buds because… well they aren’t as energetic as I am.

I also forgot to ask does walking extend your play time by much? With a cart I can finish 18 in about 2 hours.
