Hi Johanna!
Thank you for bringing your question to the Disney Parks Moms Panel!
One of the biggest surprises I found on my first trip to Disneyland (also for a race) was how close everything is there. All three of the
Disneyland Resorts are within walking distance to the start line, both theme parks and Downtown Disney. There are also many Good Neighbor Hotels that are within walking distance to them.
Take some time to explore your options on the
runDisney Disneyland travel page. Selecting your event on that page will take you to a separate website where you can find all of the hotel information and even book online. You can also call 407-939-4786 to find out more.
If I could recommend one resort, I highly recommend
Disney's Grand Californian Hotel & Spa. Not only is it gorgeous and extremely convenient to the race, but it also has wonderful restaurants and it's own entrance into Disney California Adventure park.
I hope this helps! Please let me know if you have any other questions.
