The Loch Lomond Beastie Triathlon Festival 2023

Organiser's Description

Loch Lomond Beastie Triathlon Festival 2023

Organised by Lomond Swimming & Triathlon Club


The infamous Loch Lomond Beastie Triathlons will be held in and on the banks of Loch Lomond at Balloch Castle Country Park  on the morning of Sunday July 16th 2023.

Set in the beautiful and historic Balloch Courty Park on the stunning banks of Loch Lomond. The Beasties are one of the most challenging and exciting range of triathlons in the UK.  The three options are:

  1. The Beastie comprises a 750m swim in the Loch, 17k off road cycle (three big laps) and 5k run (two laps), finishing in front of the castle, sounds a lot easier than reality and a challenge for even the most experienced of triathletes.
  2. The Wee Beastie a 400m swim in the Loch, 9k off road cycle (two smaller laps) and a 3km run (one lap). A proper wee toughie and a great way to start of before taking on the full Beastie another time, still a great achievement and not to be taken lightly.
  3. The Bikeless Beastie Aquathon a 750m swim and 5k run (two laps), this year it is the Scottish Aquathon Championship.

We have some rules and advice:

  • Mountain bikes are compulsory, the course isn't suitable for cyclocross or hybrid bikes and drop handlebars are not allowed in cross triathlons. A hardtail is best but full suspension works too. The course can be muddy so big grippy tyres are advised.
  • Wetsuits are compulsory if the temperature of the water is below 14C and are not allowed if the water temp is above 22c (24.6C if you are 60+)
  • Parking in the country park is limited so best to park at the National Park HQ or Lomond Shores, there will be changing facilities (tents), bag drop, toilets and catering, however there are not access to showers (there is a big Loch).
  • there will be Tr Scotland officals in attanednace to help us with any queries and rules on the day, however please famaliarise yourself with the rule linked below.
  • The triathlon is organised and run by volunteers from Lomond Tri Club, we do our best to provide a super experience for everyone, keeping all athletes safe and supported. It is compulosry to smile at the Marshalls.
