The Read Great Things 2021 Sprint was a supplementary reading challenge announced in September 2021. To complete the challenge, you had to finish 3 books between September 1, 2021 and December 31, 2021 that were not also counted towards your Read Great Things 2021 Challenge (the bigger list) and that was it.
Each year, winners of the Read Great Things Challenge can opt into getting a prize to celebrate their accomplishment.
The 2021 prize was a metal water bottle and the SPRINT prize was a button.
