The Festival of Endurance

Sunday 7th July 2019

We are pleased to announce that the Festival of Endurance will return on Sunday 7th July 2019.

Due to popular demand the Gauntlet half iron distance triathlon is returning with athletes racing alongside the full iron distance or Bastion competitors around much the same course.  Whilst these two epic triathlons are taking place a further 4 sets of endurance challenge races are taking place including an Aquabike, an Aquathlon, Long Distance Running and Long Distance Swimming making this a true celebration of the art of “going long”.  Please read on for more details.

The Bastion

3.8km/180.2km/42.2km – Full iron distance race.

Set in close proximity to London and in the heartland of Henry VIII’s old hunting grounds, each leg of the Bastion has been designed to offer the ultimate physical challenge to athletes but in the most beautiful setting. The Bastion, which were the final strongholds of medieval castles, features an iridescent 3.8km river and ornamental lake swim, a true toughie of 180km bike course with 2,700m of climbing and a 42.2km trail run that takes place largely off road and incorporates the gardens of both Hever and Chiddingstone Castles. You won’t get a personal best over this distance but you will have the bragging rights to arguably one of the toughest and most iconic races of its kind anywhere in the world.

The Gauntlet

1.9km/90km/21.1km – Half iron distance race.

The half iron distance equivalent of the Bastion, we call the Gauntlet, was 2018’s venue for the British Middle Distance Championships and filmed by Channel 4.  Again no chance of a PB on this super-tough course but you will have undertaken a huge challenge of one of Europe’s most beautiful races.

Long course training distances

We are offering you the chance to swim, bike or run sections of The Bastion, arguably the most grueling Full Iron distance course on the planet. Fully timed and fully supported just like those taking on the iron-distance race alongside you.

The perfect training ground to prepare for any iron-distance challenge or to get an idea of what might await you next year should you return for the ultimate Castle Triathlon Series challenge and take on The Bastion in 2019. This is a fantastic training race set in a stunning location in mid-summer, perfect for those taking on an iron-distance in the second half of the year.

The Aquabike Challenge

Distances

  • 1.9k swim: 60k cycle: 4k optional run (Laps 1:1:1)
  • 3.8k swim: 120k cycle: 4k optional run (Laps 2:2:1)

There’s a training option for everybody who’s into long distance.  After the unique swim you’ll head out on the fully marshalled and signed bike course with supported feed stations. This circular cycle route will take competitors out of Hever Castle, up through the High Weald of Kent before passing through and over the Ashdown Forest and into the village of Maresfield.  After a quick tour of the village competitors retrace their steps to the top of the forest before returning to Hever via the historic and quintessentially English villages of Groombridge, Fordcombe and Penshurst.  Finishers have the option of finishing with a gentle 4K run that circumnavigates the lake and stunning grounds of the Hever estate.

The Aquathlon Challenge

Distances

  • 1.9k swim / 10k run (Laps 1:1)
  • 3.8k swim / 21k run (Laps 2:2)

After the unique swim (1 or 2 loops), competitors will then embark on the 10k/21km run course, which follows largely off road tracks and bridle paths between Hever Castle, through the historic local village of Chiddingstone, before finishing right in front of the Castle.

The Duathlon Challenge

Distances

10.5km / 45km / 4km (Laps 1:1:1)
21.5km / 90km / 10.5km (1:2:1)

After a unique run (1 or 2 laps) through the glorious Kent countryside and around the private estates of Hever and Chiddingstone Castles, cycle up to the highpoint of the Ashdown Forest (1 or 2 laps) before finishing off with further laps of the beautifully manicured gardens and local network of paths and trails.

The Hever Marathon

26.2 miles

After the huge success of the inaugural event in the 2018 Series, the marathon returns to the atmospheric Festival of Endurance at Hever Castle.

Forget the city marathon, and fill your lungs with country air and stunning scenery before you conquer your marathon by a castle drawbridge. This new marathon, promises the most stunning off road course in the UK, a truly motivational and beautiful route that will distract you from the challenge itself. The four-laps take in two castles, two lakes, quaint Kentish villages, oast houses and with spectators and locals cheering you on all the way!

Marathon Pacer Timings : 4.00hrs, 4.30hrs, 5.00hrs, 5.30hrs (this is slower paced course than many road ones –  4.30hrs on this course is equivalent to a 4.00hrs on a road course!)

The Hever Half Marathon

13.1 miles

Take on the half marathon at our 2019 Festival of Endurance, on the most stunning off road course in the UK.

Starting at the drawbridge of the Hever Castle, this two-lap course takes in two castles, two lakes, quaint Kentish villages, oast houses with spectators and locals cheering you on all the way! Finish your race with a big celebration, medal and finishing line banquet in sight of the castle.

Half Marathon Pacer Timings : 1.45hrs, 2.00hrs, 2.15hrs, 2.30hrs

The Hever Long Distance Swim

  • 1.9k circuit
  • 3.8k circuit
  • 10K Marathon Swim (NEW in 2018) Entry tickets available to Individuals and Relay team of 5 (each team member takes on the 2k loop circuit).

The swim course leaves from the Italianate loggia taking competitors down the length of the main lake and heading into the scenic river section.This tributary of the River Eden wraps around 16 Acre Island allowing spectators to watch and cheer competitors on from only a few meters away. The Speedo team will be on hand to welcome you at the finish, then it’s time to relax and enjoy a complimentary bacon roll back at the Event Village.
