Gray and Black Tanks: Where to Dump Them
How much water to carry, how to keep the fresh tank clean, where to dump gray and black water, which products to use, and what federal rules say.
Trail running, snow, water, nature and destinations
Nolwenn covers trail running, snow, water, nature and destinations for Outfarer. Curious about everything, from meteor showers to night-train schedules, she has a knack for digging up the one detail that changes everything, and nailing it in a single sentence.
The team’s spark plug: endlessly curious, enthusiastic, idealistic, and a little rebellious beneath her impeccable manners. Nolwenn gets as excited about a starry sky as about a well-timed train, and will always take a precise fact over a brochure superlative.
She knows the meteor-shower calendar by heart, collects European night-train schedules and follows mountain weather the way other people follow their favorite team. With Outfarer since 2026.
On Outfarer, she writes about trail running, snow, water, nature, and travel: getting ready for a first trail race, choosing a marked snowshoe route, knowing where to find the mountain weather forecast, watching the night sky or wildlife without disturbing them, and getting to a trailhead by train instead of by car.
Her method: official sources for rules and safety, published data for distances, schedules, and seasons, and always precision over hype. She points out what changes from one country to the next and what depends on the day’s conditions, so you head out with reliable benchmarks instead of brochure promises.
She also keeps her articles up to date: when a schedule, an access rule, or a season changes, or a reader reports a mistake, the article is reviewed, expanded if needed, and the update date appears under the headline. A factual correction is always noted at the bottom of the page.
