If I was going to improve Modern Pentathlon (not that I really it needs to be), I would eliminate Equestrian. In Equestrian’s place I would Sport Climbing.
Why? It fits the IOC’s modern and urban agenda. It’s unique from the other disciplines of modern pentathlon, and it requires some unused skill sets. I would add lead Climbing just to be clear. My format would be: 200m Swim, Fencing Ranking Round, 1 lead climb, Fencing bonus round, laser run (distance increased to 5km). That’s just my ideal format, I sure there’s many other opinions out there. I thought I’d just share mine.
