It's just szarvas. Like the town where this etappe started.
The -félék means kind/like, so szarvasfélék = "deerkind" means belong to the group of species that generally called deer. Since they are quite a few deer species. Like dámszarvas, gímszarvas, rénszarvas = reindeer
Fun fact, the name szarvas is a step-in for a taboo word, it means "antlered one". Deer was considered a holy animal, a totem, in ancient Hungarian folklore and saying the original name of the animal was taboo, so they used the description of it. Same with wolf.
