Event unlocks when free 25 km are exceeded?

Hello!

I’m just getting back to Zwift after summer, and haven’t restarted my subscription yet. As riders receive 25 free km per month, I was planning to use these before renewing my subscription. However, I’m keen to do one of the Zwift 10 year anniversary rides (45 minutes/ride), which takes place during this weekend and unlocks Zwift’s 10 years’ anniversary kit. Likely my free 25 km will end before the 45 minutes ride is over. I am aware that one is allowed to finish the ride although the 25 free km are passed, but does anyone know if you will get the perkrs such as theme ride kit unlocks if you exceeded the free 25 km during the ride?

Thank you in advance!

Late Join is on for those rides so you can join till 29m59s into the ride and only have to do 15 minutes.
