I have not compiled the list of championship courses you are looking for, but I am walking the courses in my head now
.
None of the courses are hard to walk if you are used to walking as you do now, but as others have mentioned there are some large walks between tees or getting to next 9 which you would have to hustle to keep up. IMO very doable and in most cases you can hop on your playing partners cart.
I would not try Palmer first as it is just plain big, i.e., lots of space between holes. I would start with Hacienda, Mallory or Cane to see how it works. If you get hooked up with me, I will give you a ride between tees
I would walk myself, but as I get older I find the cooler with ice is just too much!
BTW, I have been matched up twice with gentlemen that walked and neither time was an issue.
As far as resentment? Slow play is resented (possibly too strong a word), but I see no reason why it is anyone's business as long as you keep up. The big downside to walking is it is not as social if everyone else is riding.
Have fun!
