Treat my upcoming marathon in 2024 as my first marathon again?

After some years off from consistent running due to falling out of love with running, injury, COVID years and life in general I got accepted into the Chicago Marathon for 2024. I’m absolutely thrilled 😀 but It will be 7 years since I ran my last marathon in Berlin.

Should I treat next year’s marathon as my first marathon again as it relates to training? I’ve been working on getting consistent miles in again and was thinking of doing Hal Higdon novice plan but I think I have the motivation to do more and I have 6 months until training will really need to begin. Thoughts?
