Enjoy the scenic grounds of Belvoir Castle in this multi-sport weekend for the whole family. Test your open water swimming in the estate's very own lake, cycle through the undulating countryside, and run through the castle's iconic grounds.

Route information
The transition area is nestled in the grounds looking up to the grand Belvoir Castle.
The Lake Swim: The open water swim takes place in a calm lake at the foot of the Estate with sights up to the castle, the swim is a multi lap swim. The swim is also perfect for those new to open water triathlon as you're never too far away from the lakes edge or your supporters. All competitors will be placed in start wave groups which will be confirmed closer to the date of the event.
Bike: All distances (other than the Super Sprint) is a multi-lap course with a challenging undulating profile through the idyllic vale of Belvoir villages. There are one or two sharp and gradual inclines that prove a good test of mental, physical strength and determination but you will be well rewarded with a route of discovery through quaint villages and quiet country roads.
The Super Sprint bike leg is one undulating lap.
Run: Feel the history of the land and be surrounded by ancient trees adorning your run, finishing with a scenic multi-lap run on tarmac roads around the estate running up to the Castle itself and then onto your Finish with the Castle creating a momentous backdrop for your free Finishers Photo download.

Did the race in 2022
The run from the swim to the transition area felt like way further than 300m they said it was so that was a bit if a shock but this was my first ever triathlon and everyone was super helpful and friendly telling me what to do and what to expect. I'd highly recommend it.
Did the race in 2022
On the whole a Great event! Few points to improve 1) more portaloos I had to que for around half an hour and nearly missed my wave start. 2) better marshalling! I missed the return entrance (adding 5 minutes onto my time) from the bike course due to the Marshall being distracted and lack of signage. A simple BIKE FINISH/IN sign would of prevented this. On the whole great course, very tough which is what I wanted. See you next year!
Did the race in 2022
Great event and great day thanks Swim start was late for some reason Did not find event route info online easy to understand for swim/bike/run but used GPX for bike and that was very good . Spotted a few people struggling with run route while racing especially the add on field loop for the 1/2 dist But email enquires answered almost instantly before hand thanks Hopefully see you next year
Did the race in 2022
Nice little triathlon. Swim was a little muddy, defo more 550m than 350m run to transition....the bike course was really nice.
Did the race in 2022
A hard course but not unexpected. Very well organised and a fun event all round whether you are a novice or medaller
Did the race in 2022
Tough course in a lovely setting, with a friendly and supportive atmosphere. Will definitely return.
Did the race in 2022
All round great day
Did the race in 2022
Not enough toilets!! Only 6??Course was good, info and updates before hand were clear. Very few supporters / atmosphere compared to past events. For the price of the entry (£75) feel a little short changed.... wooden medal at the end and nothing else. Previously I have had a water bottle / food / a beer included and a t-shirt all included in the price. One person arranging the swim waves was not enough, could not hear the times/waves being announced and nearly missed my slot despite being there 30 minutes before!
Did the race in 2022
Great weekend, organisation was excellent, cycle route had a great mix of uphill/ downhill sections
Did the race in 2022
Will be going back next year
