Mountain rescue teams, the Met Office and the Countryside Code all start in the same place: know how long your route takes, what the weather will do up high, and who knows where you are.
Pick a route to see the walking time Naismith's rule gives, before breaks. The bar shows how much of a short winter day it would use.
Naismith's rule as described by UKHillwalking: 1 hour per 5 km plus 1 hour per 600 m of ascent. Real times vary with fitness, ground and weather.

VOLUNTEERS · MOUNTAIN RESCUE
The Met Office mountain forecast shows wind, gusts, temperature, a feels-like temperature and the freezing level at 300 m height intervals, and is issued daily before 6pm.
FOUR CHECKS BEFORE YOU GO
Ten minutes now, an easier day later.
These come from Mountain Rescue, Met Office and Countryside Code advice. None needs special equipment, only a little time the evening before.
Time the route
Use Naismith's rule to estimate the walk, and have a shorter alternative ready for tiredness or bad weather.
Read the mountain forecast
Check wind, feels-like temperature and freezing level for the height you will reach, not just the valley.
Leave your plan
Tell someone reliable your start, finish, expected return time and alternatives, and let them know if it changes.
Charge the phone
Keep one charged phone in the group for emergencies, plus a paper map, which needs no battery.

IF SOMETHING GOES WRONG
Make the call count.
Dial 999 or 112, ask for the Police and then Mountain Rescue. Have ready your location (a grid reference is best), the casualty's name, age and injuries, the number in your party and your mobile number. Do not move until the team contacts you.
If you have hearing or speech difficulties, emergencySMS lets you text 999, but only if you register first by texting register to 999. To signal by whistle or torch, give six long blasts in a minute, pause for a minute, and repeat.
Questions
Questions people ask
How long will my hill walk take?
Naismith's rule, devised in 1892, allows 1 hour per 5 km on level ground plus 1 hour for every 600 m of ascent, about 10 minutes per 100 m. Add time for breaks and slower walkers.
Who do I call for Mountain Rescue?
In England and Wales, dial 999 or 112 and ask for the Police, then Mountain Rescue. The Police alert the team. Scottish Mountain Rescue gives the same advice.
Can I text 999?
Only if you have registered for emergencySMS, which is for people with hearing or speech difficulties. Register before you need it by texting register to 999.
Do I need warm clothes in summer?
Yes. Mountain Rescue advice is to carry spare layers, a hat and gloves even in summer, because the tops are colder and windier.
Does my dog need a lead on the hills?
The Countryside Code says that between 1 March and 31 July you must keep your dog on a lead on Open Access land, and always on a lead near livestock.
