Since there doesn't seem to be a separate article for paralympians, perhaps there can be a new section for them? Notably, Kendall Gretsch has won gold in both winter (Peyongchang, biathlon & cross-country long distance) and summer (Tokyo, triathlon). Matthall.research (talk) 00:52, 15 January 2022 (UTC)[reply]
I would guess that is because there are more common among paralympians to participate in both sets of games than there are for regular summer and winter games. So the list would be very big to include all medal-winners who won medals at both sets of games. Best regards Migrant (talk – contribs) 17:59, 15 January 2022 (UTC)[reply]
I think a new article is the best. Otherwise it would be a very long list. Besides that the Olympics and Paralympic are different events. --Micnl (talk) 11:56, 16 January 2022 (UTC)[reply]
