Intro: Run4Adventure’s First day CHAMONIX traditions | Being back in the town we love so much offers a solid template for tackling high-altitude running. Here’s what they do on arrival—a practical session you can adapt to your local conditions.

Key Points:

• The pair begin their Chamonix adventure by hitting the Vertical Kilometer (VK) trail—a punishing ~1 km climb that demands about 30 minutes of sustained effort.
• They emphasize the value of “shocking your physiology” at altitude, working through ladders and cable-assisted sections on technical terrain.
• Partway up, they stop briefly to catch their breath before making a push toward the top, paying close attention to breathing rhythm and heart-rate response.
• Following the VK comes a 4-mile gentle run down by the river (easy pace, no pressure to chat) and the day wraps with coffee, pastries, and a meal overlooking the peaks.
• Smart execution looks like: start conservatively, grip the handrails on steep passages, walk when you need to reset your breathing, and fuel up with carbs ahead of the descent.

Workout Example:

1. Warm‑up – 5 min easy jog on flat terrain.
2. Vertical Kilometer Run –
   • Tackle the VK (≈1 km elevation, ~30 min).
   • Maintain a steady aerobic pace (≈70‑75% max HR).
   • Use handrails or cables on steep ground and take walking breaks if breathing gets ragged.
   • Work on steady breathing: nose in, mouth out.
3. Cool‑down – 5‑10 min easy jog back.
4. Optional Shake‑Out – 4 mi (≈6.4 km) on flat river terrain at a relaxed clip.

Closing Note: Lace up, find a steep climb near you (Chamonix’s VK if you’re lucky), follow with a mellow recovery loop, and grab a coffee afterward. Use the Pacing app to dial in the right effort for where you’re at, soak in the scenery, and enjoy the run.
