I am kind of unclear on the original question. You are considering a "race next year at WDW during one of the race weekends." For three of those races in 2024, marathon weekend in Jan, Princess half marathon weekend in Feb, and Springtime Surprise weekend in April, we are well beyond the 7-month reservation window and thus getting anything will likely be difficult.
If you mean the Wine & Dine race weekend, which next year is Oct 31 to Nov 3, then be aware that race weekend is in the high to extemely high
DVC demand "fall" season which runs from late Sep to marathon weekend in Jan, and the Wine & Dine race weekend is one the highest DVC demand times of the year (the same would apply to the Jan race weekend). If you are considering reserving at 11-months out and then switching part at 7-months out, then finding anything, even at SSR, could be difficult at 7-months out for that weekend.
If you mean making two 11-month reservations for a split stay, you can find openings, except the following disappeared very fast right at 11-months out for the Nov 2023 Wine & Dine race weekend: (a) BWV: all rooms except pool/garden view 1BRs (but part of the cause is that all boardwalk view rooms were closed for much of Nov; usually it is only the standard and boardwalk view rooms (including GVs) that disappear that quick, although even pool/garden view can go fairly quickly after 11-months out); (b) BLT standard studios and 2BRs (including dedicated 2BRs); (c) VGF Deluxe Studios and 2BRs, and the GVs, (but not the Resort Studios); (d) Riviera tower studios, and standard studios and 2BRs (d) CCV both shower and tub studios and 2BRs; (e) AKV value and club level rooms, all sizes; and (f) the OKW GVs in the near Hospitality House booking category.
If for any of the other three races, you actually mean year 2025, then you can assume the Jan race weekend will have problems similar to the Wine & Dine race weekend.
The Princess half-marathon weekend is actually the highest demand time that exists between mid-Jan and late Sep, and although lighter than Nov and Jan, getting anything at 7-months out could be difficult, although possibilities might exist for Kidani savanna view rooms, SSR, and OKW. At 11-months out from the Feb race, rooms will remain open for some time longer than for the Wine and Dine race weekend, except the following will likely disappear very quickly at 11-months out: BWV standard view studios and 2BRs, AKV value and club level studios and 2BRs, BLT standard studios and 2BRs, and Riviera Tower studios.
The Springtime Surprise weekend is still in its early years of development and its usual demand is still being developed but will probably remain lower than the Princess half-marathon weekend. It is higher than other times in April, although April outside of Easter week and that fairly new race weekend, is among the lower DVC room demand times of the year. Likely , the same rooms as the Princess weekend will disappear quickly air 11-months, except possibly Riviera Tower studios, and more appears to be available at 7-months including Poly.
