Sprint Triathlon (formerly Short)

400m swim, 18km cycle and 5km trail run
Category: Triathlon
Event Grade: Moderate

In order to create one of the most thrilling triathlons in the country we have devised exciting routes for both the long and the sort triathlon events. The short route whilst less technical than the long still has some challenging ascents, descents and features on open roads which area narrow in parts.

It’s therefore our advice that only riders who are confident in their use of TT bars and aero bars on the open road use them for this event.

Starting times will commence from 8am.

Route Description

400m Swim

The use of swim socks, gloves and neoprene hats are all permitted making the swim a comfortable pleasant experience. The routes can be observed from the Festival Village and swimmers can be cheered as they exit the water to transition. Please note: water temp for this event will be around 14oC and you should prepare yourself accordingly - read Acclimatising to cold water article.

18km Cycle  

A stunning ride going North from Crow Park to Great Crosthwaite, then south alongside Fawe Park and Swinside, heading to a steep ascent and some sharp turns approaching Brandelhow Park. While climbing Catbells stunning scenes of Derwent can be seen to the left. The route continues south with a steep decent, narrowing on the approach to Manesty Wood, towards Grange. Exit Grange over the River Derwent the route heads back north through Borrowdale Valley, past Shepherds Crag and Lodore Wood and alongside Derwent Water and the Great Wood into Crow Park. 

All participants are responsible for ensuring their bike is safe and road worthy.  A helmet must be worn and secured before you will be allowed to take your bike out of the transition area.

The route will be signed and marshaled as appropriate, however it is the responsibility of all participants to make sure they are aware of the route and abide by the highway code at all times when on or near public highways.

5km Trail Run

From Crow Park participants will experience a mix of road track and fell path with stunning views all around from the start. Heading east from transition participants will run through Cockshot Wood before taking the trail path alongside the Borrowdale Road, heading south. 

At Calfclose Bay participants will take the lakeside road north towards The Ings with breathtaking views of Derwent Water and along the lakeside back to the finish line in the event village at Crow Park.

All participants are advised to wear trail running shoes for the event to provide you with both comfort and stability during the run. The route will be signed, flagged and marshaled as appropriate, however it is the responsibility of all participants to make sure they are aware of the route and abide by the highway code at all times when on or near public highways.

It is possible that events and courses at KMF may need to be amended at short notice due to weather issues, water levels, road conditions or roadworks.


It is possible that events and courses at KMF may need to be amended at short notice due to weather issues, water levels, road conditions or roadworks.

By nature, many of these factors are not possible to know well in advance. For each event there are a number of alternative options available which can be implemented at short notice. The organisers and race directors will always have athlete and spectator safety as the highest priority, and within that context will seek to provide the best possible experience. All sporting events would be impacted if the KMF Festival Village has to be closed. In this instance, as long as circumstances allow, all starts and finishes would be relocated to Lake Road and Lakeside Car Park and the events operated as smoothly as possible.

Swim: The prevailing wind direction is from the SW (i.e. along Derwentwater). There are options available to us to keep the event operating in high winds - keeping the swim in the lee of Derwant Isle, and starting and finishing from the beach adjacent to Keswick Launch. These would be exhausted before any cancellation decision. 

Ultimately, we would consider cancelling the swim if the weather/water conditions are extreme, and there is a risk to participants safety. This also applies if the conditions are such that the water safety team are compromised in any way, and cannot provide assured safety cover to the event. In event of swim cancellation, the event would become a rolling start Duathlon.

Bike: alternative routes are available depending on the conditions which are forcing a re-route.

Run: alternative routes are available depending on the conditions which are forcing a re-route.


What is Bio Security?
Biosecurity means taking action in order to minimise the introduction or spread of invasive non-native species and diseases (INNS).

Why should we worry?
The freshwater resources of Cumbria – its many tarns, lakes, rivers and becks – are of great ecological and economic significance. We love spending time in and on them so protecting them is something we all need to take responsibility for. Freshwater INNS are able to ‘hitchhike’ on our equipment, footwear, clothing and boats. When we move to a new river, tarn or lake, a species may be transferred and may become established, often having devastating effects.

What can we do to help?
As keen outdoor and sports enthusiasts we all need to help protect the landscapes we love. The bio security at the Festival will involve just a little extra cooperation and organisation. You will be required to ensure that your wetsuit is clean and dry before you arrive and that it is cleaned before you leave. The purpose of this is to do our bit to try and stop the spread of invasive aquatic species.

The process at the race will be:
You will ensure that all equipment to be taken into the water is clean and dry before you arrive on the race morning. After the race and before removing anything else from the transition area, go to the washing point with your wetsuit, goggles, swim cap etc, and your race number. Check your equipment for obvious vegetation or other aquatic life and remove anything found.  Wash all above mentioned equipment in the fresh water and tubs provided.  Once done to their satisfaction, a steward will mark your race number to indicate that your equipment has been cleaned. When you later leave the transition area with all of your other equipment show your appropriately marked race number to the transition exit steward who will check it against your bike number tag in the normal way.

Compliance with this process is essential to ensure that we are able to pursue our sport in such beautiful surroundings. For more information on the issues please visit http://www.cfinns.scrt.co.uk/.
