Red Lights for UTMB

Announced today via IG and email affecting all runners racing UTMB this year and beyond:

Between Notre-Dame de la Gorge and Col du Bonhomme, over a 6-to-7-kilometer stretch (mostly uphill), you must use the red-light mode on your headlamps when crossing the Contamines-Montjoie Nature Reserve. 

Why? 

Some scientific studies show that white light can disturb nocturnal wildlife, whereas red light is less noticeable to many species. 

Equipment: only one of your two required headlamps needs to be equipped with this mode. 

Today would be a good day for UTMB to announce an official headlamp sponsor for their World Series.
