Alright, assuming I've interpreted the canoe marathon qualification system correctly...

The quotas might be allocated as follows:
Women's K1 - / The America's continental quota might go to (all athletes from the region were lapped), while Africa might go to (both their athletes finished with DNF) / The short distance quotas might go to (I'm not sure how these would be affected by potential continental reallocations)
Men's K1 - / The final short distance quota might go (based off semifinal time)
As always, none of this is official, as only the international federation can confirm who qualified.
