Kit List

Bags & Packs


15 – 25L rucksack with a good waist belt. To carry your own spare clothing, water, camera, and all your personal kit including, snacks and water and a whistle for safety provisions

Kit bag

Preferably a soft duffle bag for clean clothes

Dry stuffsacks

A waterproof dry bag or  equivalent to keep phone, camera etc


Warm headgear

This can be a warm hat, beanie, balaclava, anything to reduce the heat loss from your head

Upper Body

Fleece Jacket or Wind stopper

A full zip version is easier to put on and has better ventilation than a pull over style

Waterproof jacket

Breathable waterproof jacket that has a good hood


A pair of thin liner gloves you can keep on the whole time if you need to

Base layer

This is the layer closest to the skin and its principal function is to draw (wick) moisture and sweat away from the skin. You can also get thermal base layers for use at higher altitudes that provide an additional insulative layer while still drawing sweat during times of high exertion

Lower Body

Waterproof trousers

Waterproof trousers can be of lighter weight than the top

Trekking trousers

These tend to be polyester so they dry quickly after a shower and weigh little in your pack. Consider perhaps a pair with detachable lower legs as an alternative to shorts

Cycling shorts

3 pairs or better still 1 pair for each day of riding as washing is difficult at hotels. Spend more to get more padding so you can sit easy at night!



Change of socks

Walking boots

Well broken in boots/walking shoes, suggest boots in preference over shoes/fell trainers as with tiredness comes weak ankles. Also walking in dark doesn’t afford good foot placement

Cycling shoes and over shoes

Assuming you have cleat pedals, otherwise trainers or similar

Bring your own bike if you are intent on not hiring one of ours

Travel insurance

Copy of own travel insurance details.  And relevant contact numbers.

We have a partnership with True Traveller and would recommend that you contact them when looking for travel insurance for your trip with 360. However, it is vital that you ensure that the insurance cover they offer is suitable for you, taking your personal circumstances (items to be insured, cancellation cover, medical history) into account. Many other insurance providers are available and we do recommend that you shop around to get the best cover for you on the expedition you are undertaking.

It is your responsibility to ensure that you have the appropriate insurance for your intended trip.  To include medical evacuation and coverage up to the maximum altitude of this trip.

Health and Safety

What happens if I fall ill, can’t keep up or there is an emergency?

The mountain leaders well trained and experienced and managing situations on the hill should they need to get outside assistance for example ‘mountain rescue’ they all carry mobile phones and also radios for communication with the minibus drivers. The mountain leader will always keep the group together for maximum safety on each peak and set a sensible pace for all to achieve this challenge. However if your struggling you must be honest with yourself and the leader remember the top of the mountain is only halfway!

Any tips to remember whilst trekking?

Here are a few tips to remember while trekking:

  • Hydration is important. Drink plenty of water
  • Eat plenty to keep energy
  • Trekking poles are a great way to support the knees and provide stability
  • Honesty, if you are feeling unwell at any point please let someone know, we want to make sure everyone remains fit and healthy whilst trekking.


What advice can you give on bikes?

We strongly recommend that you ride a road or hybrid bike, rather than a mountain bike, for this challenge due to the distance involved plus the route is along on well-surfaced roads. It’s important that you ride the bike you have been training on so you are used to it. Although training in the gym is useful, there is no substitute for getting out in all weather conditions and getting to know your bike including the range of your gears. Bikes can be hired for a cost £35.00 which includes a helmet.

What type of footwear should I be wearing?

The choice of walking footwear is incredibly important and should not be decided on price alone. The terrain is uneven and can be very rough so it is vital that you use a pair of strong canvas or leather boots with good ankle support, not trekking trainers, for your challenge.

Not only the boots but the socks that you wear are also very important and it is worth investing in some good pairs of socks that do not blister. Wearing your boots and socks during your training period on and off the hills will inform you of whether they are suitable for the challenge. Trainers are ideal for cycling.

What about other equipment/clothing?

You will need to bring your own helmet so that the fit will be perfect. You will not be allowed to ride unless you wear a helmet. We recommend you bring your own gloves too. They are an essential piece of kit that will relieve strain and abrasions in the event of a fall. You must also bring your own padded cycle shorts and stiff soled sports shoes are recommended if you are not wearing SPDs. Please refer to the kit list for more details.

The Challenge

What are the group sizes?

Our maximum size group is 40 with a minimum of 10 people per group.

Who will be leading the group?

We employ experienced and fully qualified mountain and cycle leaders to accompany and lead you. They are First Aid trained and have extensive experience in leading in the mountains. They will be ultimately responsible for your safety during the challenge. They will be carrying full safety equipment and mountain first aid kits with them.

What if I have problems with my bike?

Our support vehicles will carry a range of spares along with a full tool kit. However, it is impossible for us to carry spares for every eventuality so it is vital that you check your own bike is in good working order before departure. It is a condition of travel that you supply your own helmet and wear it at all times while cycling, with the straps done up!

What information can you give on the trek?

The trekking section of the challenge will take place on Snowdon it’s a steady climb to the summit taking around 3 hours, followed by the descent taking around 2.5 hours to Pen Y Pass. The trek will be led by qualified local mountain leaders.

How fit do I need to be?

Training and a good level of fitness is definitely required. This is a tough challenge! As much preparation and training you put in beforehand the better chance of success you have.

How many breaks will be taken during the trek and for how long?

The timing of breaks is quite liberal and there will be scheduled breaks for 5 minutes, the exact times and places of your breaks will very much depend on the weather and the well-being of your group. When ascending and descending in order to maintain a healthy and steady pace.

The Weather

What is the weather likely to be like?

The mountain weather in the U.K. can be very changeable, it can be glorious sunshine down at the base but be wet and windy on the summit. It is not uncommon for it to change from clear blues skies to rain and fog in moments. It is important to follow the advice we give and carry the correct kit (please see kit list).


Do I need special insurance for this challenge?

You must carry individual travel insurance to take part in the challenge. We cannot take you on the mountain without proof of insurance.

It is your responsibility to ensure that you have the appropriate insurance for your intended trip. To include medical evacuation and coverage up to the maximum altitude of this trip.

Your insurance details are requested on the booking form, however this can be arranged at a later date. 360 Expeditions will be requesting your insurance details 8 weeks before your departure.


Any tips on training?

The ideal training for the Sea 2 Summit Challenge is getting out there and actually training on your bike or in the hills walking. However, if you do not have the luxury of living in the hills or time to go out, then the stairs at home (or an office block of flats with lots of stairs) are a great place to start training. Remember to use the walking boots that you will be walking in after the first month of training to get them worn in.

If you have never cycled before, this ride is still achievable with the correct ride preparation. Start at least 3 months ahead of the ride with some short distances at weekends and whenever you can during the week. 5-10miles is not a great distance and will help your bottom and legs get used to it all.

By 3 months prior to departure, you should be able to take on some long rides, up to 30-40miles in a day, and if you live in a flat area it is well worth getting out and finding some hills. If you cannot maintain a steady average speed of 9 miles per hour you are unlikely to be able to complete the cycling.


What do you do to protect the environment?

We limit the impact we have on the surrounding environment by remaining on the paths at all times so as not to cause further erosion on the mountain. We will ensure that all rubbish is disposed of responsibly and take all rubbish away with us.

A challenging and fun day for people of all levels! Really well organised event. Everyone who organised and supported were really nice and helpful.
