Sports KOLs, Tourism Academics & Luxury Hosts - Sports Travel Trend

Working on a story that's about travelling for sports. Does anyone know of any: 1) Sports KOLs/personalities who plan their holidays around their sporting pursuits (e.g. Hyrox, biking, marathons, tennis retreats, skiing, hiking, etc)? 2) Global luxury property contacts that cater to this group of travellers? 3) Tourism, consumer academics and/or experts who can talk about this travel trend? Thank you!!
