Sounds like a good way to keep the adventure honest. Start with the basics: trail length, average slope, and elevation gain. Those give you a quick sense of how hard it’s going to be. Add weather—temperature, wind, humidity, and any forecasted storms—from a reliable API like NOAA or a local station. Check the sunrise time and how quickly the sun will move over the ridge; that tells you how much daylight you’ll have. On the ground, use a GPS unit or a map app that shows slope and elevation—Gaia GPS or Komoot do that well. Log your route and set waypoints so you can backtrack if the wind picks up or the trail conditions change. If you’re into numbers, keep a simple log: distance per hour, heart‑rate or perceived exertion, and any incidents. That data can feed into a small spreadsheet or a note app for future runs. So, metrics: distance, elevation gain, slope percentage, sunrise time, temperature, wind speed, humidity. Tools: weather API, GPS with elevation data, a mapping app that shows trail difficulty, and a simple log or spreadsheet for post‑run analysis. That keeps the hike both exciting and accountable.
