Timing the National Three Peaks Challenge

Completing all three peaks within 24 hours is achievable - but only with a realistic schedule. This guide breaks down how the time is spent, so you can plan with confidence.

How Long Does the Three Peaks Challenge Take?

The short answer: most groups take 21–24 hours to complete the challenge. Around 90% of participants finish all three peaks, but only about 40% manage it within the 24-hour target. The difference almost always comes down to realistic planning, not raw fitness.

The total walking distance is 23 miles (37km) with 3,064 metres of ascent - roughly equivalent to climbing from sea level to the top of Ben Nevis three times. Add 462 miles of driving, and you begin to see why timing matters so much.

Time on Each Mountain

These are comfortable walking times that most reasonably fit people can achieve. They include the full ascent and descent.

• Ben Nevis: 5 hours - the highest (1,345m) and most demanding, tackled first when energy is highest
• Scafell Pike: 4 hours - from Wasdale Head, the shortest but rockiest route
• Snowdon (Yr Wyddfa): 4 hours - well-maintained paths make this manageable even when tired

These aren't race times. Snowdon, for example, can take up to five hours at a leisurely pace. If you're unsure whether your group is ready, a good benchmark is being able to walk 12 miles over hilly terrain comfortably, or completing Snowdon in under 4 hours.

Driving Between the Peaks

The drives are longer than most people expect - and they're where many self-organised challenges go wrong:

• Fort William to Wasdale Head: approximately 6 hours (via Glasgow and the M6)
• Wasdale Head to Snowdon: approximately 5 hours (via the A55 coast road)

This is where dedicated drivers make a real difference - walkers can rest during the transfers, arriving fresher for each climb. If you're attempting this without professional support, never try to walk and drive yourself. Fatigue is dangerous on mountain paths and motorways alike.

Avoiding Traffic Problems

Traffic is one of the most common reasons groups miss the 24-hour target. The M6 corridor around Manchester and the Glasgow area are particular bottlenecks, especially on bank holiday weekends and during summer Saturdays.

Before setting off, check for roadworks on your route - losing 30 minutes to an unexpected lane closure can throw off your entire schedule. A midday start from Ben Nevis (finishing around 5pm) means you'll typically clear the worst traffic zones before they build up.

Recommended Schedule: 6am Start

This is the itinerary we use on our Guided and Private challenges. It puts the two hardest peaks in daylight and leaves Snowdon - with its clear paths - for the night section.

6am	Start Ben Nevis
11am	Finish Ben Nevis, begin 6-hour drive to Scafell Pike
5pm	Arrive at Wasdale Head, start Scafell Pike
9pm	Finish Scafell Pike, begin 5-hour drive to Snowdon
2am	Arrive at Snowdon, start final climb
6am	Finish Snowdon - challenge complete

Alternative: Midday Start (Best for Traffic)

Starting Ben Nevis around midday avoids the worst traffic on the drive south. You'll climb Scafell Pike overnight and tackle Snowdon in the morning light. This works well if you're arriving in Fort William the evening before and want a proper night's sleep first.

12pm	Start Ben Nevis
5pm	Finish Ben Nevis, begin 6-hour drive to Scafell Pike
11pm	Arrive at Wasdale Head, start Scafell Pike
3am	Finish Scafell Pike, begin 5-hour drive to Snowdon
8am	Arrive at Snowdon, start final climb
12pm	Finish Snowdon - challenge complete

Alternative: Evening Start (Maximise Daylight Walking)

If you have dedicated drivers and prefer to walk in daylight as much as possible, this schedule works well. Walkers can sleep during the overnight drive to Scafell Pike, arriving rested for the morning climbs.

5pm	Start Ben Nevis
10pm	Finish Ben Nevis, begin 6-hour drive to Scafell Pike
4am	Arrive at Wasdale Head, start Scafell Pike at first light
8am	Finish Scafell Pike, begin 5-hour drive to Snowdon
1pm	Arrive at Snowdon, start final climb
5pm	Finish Snowdon - challenge complete

Best Time of Year

We recommend taking on the challenge between late May and late September. Longer daylight hours - peaking around the summer solstice in late June - give you more flexibility and make navigation easier. Outside this window, shorter days and unpredictable mountain weather increase the difficulty significantly.

Be aware that bank holidays and weekends around midsummer are the busiest times on the roads. If you can travel midweek, you'll have a smoother drive.

Common Timing Mistakes

Most failed 24-hour attempts share the same problems:

• Underestimating the drives - 11 hours is the minimum. Traffic, fuel stops and toilet breaks add up quickly.
• Starting too late - if your Ben Nevis descent runs long, every subsequent stage is pushed back.
• No buffer time - the schedules above include some slack, but not much. Poor weather or a slower-than-expected climb can eat into your margin.
• Driver fatigue - if your drivers are also walking, everyone suffers. Professional challenge providers use dedicated drivers for good reason.

Can You Do It?

The Three Peaks Challenge is demanding but achievable for anyone with reasonable fitness and proper preparation. You don't need to be an athlete - but you do need to train. Most people benefit from 8–12 weeks of preparation, building up to regular 10–12 mile walks over hilly terrain.

If the 24-hour target feels too ambitious, consider joining a supported challenge where the logistics are handled for you, or speak to us about a more relaxed multi-day itinerary. The mountains aren't going anywhere.
