SAFD: My first RunDisney experience was the half marathon during Marathon Weekend 2013. My wife wanted to do a cruise and I promised if she could do a half marathon, then we'd go on a cruise. She did an awesome job of getting in shape and we did the half marathon on Saturday and then got on the Disney Dream on Sunday.
We returned to RunDisney in 2018 when following knee surgery I decided I wanted to try a marathon (I went all in on Dopey). I had seen a live stream of the marathon and saw all kinds of people finishing in 4 hours and it inspired me, despite my first thought when I crossed the half finish line in 2013 being "I can't imagine turning around and doing that again."
I have only participated in Marathon Weekend, and that remains my focus.
2013: Half marathon (no training, other than just being in shape)
2018: Dopey (ran 5K, 10K, marathon -- did half with my wife)
2020: Dopey (hot! and still did parks)
2022: Dopey (focused more on running, didn't do parks, avoided people so we didn't get sick before a cruise we had scheduled for the day after the marathon)
2023: Marathon
2024: Dopey
2026: Dopey (didn't run the half or full due to injury)
I've wanted to try other weekends, but after doing Marathon Weekend so much, it doesn't seem "worth" the trip from PA for the other weekends. Plus, Marathon Weekend just seems to be the premiere weekend, and I enjoy it so much. It also fits best with our schedule for traveling.
