You don't want to be "practicing" your landing on a minimum length field, you had better show up already "practiced". For landing the secret to making the book numbers is an accurate touch down point at the correct speed. The good news is you can practice that on every landing.
Well, I'm not that good, I'm afraid.
For example I can do crosswinds (to some limit), and I can do short runways (to some limit), but I'm really not keen on trying my maximum tolerable crosswind and my minimum tolerable runway length at the same time - I'll go somewhere else that day. If I'm concentrating on a crosswind at the limit of my ability I'm not really very interested in having to worry about runway length at the same time.
I do fly for fun, after all.
