I think 'Kilian training above Montenvers' by Tristan Shu is the best trail running photo ever.
What makes it even more exciting for me is the fact that I'll be running the Mont-Blanc 80K there in 2 months! The scenic and technical course goes through Montenvers at France's largest glacier Mer de Glace before finishing in Chamonix.
At the moment there is still plenty of snow in this area. I hope the weather will turn sunny and warm so it will all clear by June 28th.
