Starts
All four races are showing 6 starting groups. That means for the most part that the 5k/10k start group assignment is simply your estimated pace with an extra group in there for some sort of spreading. Under 8 min pace = s1, 8-10 = s2, 10-12 = s3, 12-14 = s4, 14-16 = s5
The HM/M are similar.
Finish Line
5k
New 5k course for Marathon Weekend. It matches the 2021 Wine and Dine 5k course. Now includes Remy and Imagination/Land/Sea. Unlike 2020, you do get to run past the EPCOT ball.
10k
Completely new 10k course. I'm not finding anything similar since at least 2011. Far less EPCOT time compared to the normal 10k course (
link). No Boardwalk, only Yacht/Beach Club. But you do get more DHS than you've been getting recently. Since DHS isn't open when the balloon ladies would clear it (6:00am start and 64 min to point = 7:04am). DHS opens at 9am per the Disney website. It seems like a smart idea. There's about 3.5 miles of highway time which is roughly the same as the old course as well.
HM
HM is almost the same as 2020. There is a small change in MK as you go back to the backside of Fantasyland (which 2020 shows you did not). With that being said, none of the mile markers are in different places post that change. So a little suspect. And then in 2022 you go past the EPCOT ball which you didn't do in 2020.
M
Mostly the same course as 2020. 2020 had backside Fantasyland, 2022 does not. BB out and back and then parking lot with no park time in 2022. Quick exit of DHS like in 2020. Closer to EPCOT ball in 2022, than 2020, but not like the classic finish in 2019.
I like the use of the 10k to get more DHS time that the M seems to have to avoid now a days.
