The route
Know the
challenge.
Source event documents identify Y Lliwedd, Yr Wyddfa and Garnedd Ugain. Challenge Central is reconciling the final approach, descent, start transfer and operating timings before these figures become definitive.
Why details are held back The named peaks, distance and ascent will appear only after the Challenge Central route and operating plan are approved.
Is it for me?

Achievable.
This is a demanding mountain day, not a technical climbing event. You should expect sustained walking, changing weather and uneven ground. A focused training plan and the right kit will help you arrive ready.

Before you
take it on.
Which three peaks are included?+
The current approved source material identifies Y Lliwedd, Yr Wyddfa and Garnedd Ugain. The final route and operating timings are still being reconciled.
Can my team register its interest now?+
Yes. Organisations can discuss Snowdonia as part of a wider Three Peaks Series programme while the final operating plan is completed.
Do I need mountaineering experience?+
The Series is designed as a walking challenge rather than a technical climbing event. You do need appropriate fitness, mountain-ready kit and respect for changeable conditions. Final requirements are confirmed for each event.
Can our company complete the Series over several years?+
Yes. A team can build its collection across a one-to-three-year programme, and the same employees do not have to attend every challenge.
Do the challenges have to be completed in number order?+
No. The numbers identify the five collection pieces; they do not set the order. Start with the challenge that works for your team.
