End reward: Pikachu with a marathon visor costume encounter

Is there another way to get Pikachu with a marathon visor in the 'Fall Marathon: Buddy Trek' event?
There is not. As with the 'Spring Marathon' and 'Summer Marathon' events earlier in the year, this is the only way to get the marathon visor Pikachu costume during 'Fall Marathon: Buddy Trek', and that's through Timed Research.
This also means there's just one attempt at a getting a shiny during the event. However, since this costumed Pikachu has already appeared twice previously, there's a possibility it'll show up again before 2026 is out; could we see a Winter Marathon event, for example?
(This is speculation on my part, but either way, it's likely you'll have another shot at a marathon visor Pikachu one day - even if the Marathon event returns in the Spring next year.)
Here's how the costumed Pikachu looked in the Summer Marathon event:
