Meet the organiser

Always Aim High Events was founded in 2010 by Tim Lloyd and Nigel 'Kenny' Kendrick. The first event was the now iconic Slateman Triathlon 2011 attracting just over 400 competitors (it now regularly exceeds 1,000), with a vision that included the Snowman and Sandman - the three events which now make up the Adventure Triathlon Series. From that one event we now host 34 all inclusive events over 9 weekends, with many more planned for 2019 and beyond. In 2015 Always Aim High Community Events was set up as a not for profit organisation to help with engaging with and hosting local community events. At Always Aim High we are extremely proud about delivering the UK's ultimate triathlon, cycling, running and swimming challenges in the most beautiful and iconic locations that we can find. From epic mountain, coastal and city triathlons, to breathtaking cycle sportives which cover the length and bredth of Snowdonia, there's something for everyone at Always Aim High Events!

  • Did the Marathon in 2019

    Brilliantly brutal event. Nothing prepared me for "running" up a mountain. The "path" up was anything but, I'd call it scrambling although I'm sure experienced people wouldn't! One you must do, but probably only once! The aid stations were pretty poor with only fruit and gels at some stations. This would have been very basic for a normal rod marathon let alone a tough one that took me 8hr30 - the guys and girls doing the ultra would have had the same.

  • Did the Marathon in 2019

    A stunning route with a mix of challenges. Very well organised and route is well marked out. My knee went quite early on so I had to walk the final 13miles!
    The climb up to the summit is beautiful, busy with walkers also but we just pushed them off the mountain (joke!). We were very fortunate with the weather, it wasn’t too hot or too cold, I ran the whole race without the need to pull on a long sleeve top or remove layers. The aid stations are well placed out but I strong recommend ensuring you can carry at least 1 litre of water plus electrolytes, I found I was refilling my bottles at the final 2 (or 3 aid stations).
    Fantastic support from spectators or walkers passing by, the marshalls were very friendly and encouraging too - big up to Beddgelert Marshall ‘Sean’ for walking the final mile with me.
    A very painful downhill descent and finally crossing the line in 8hrs 15mins led to a very emotional finish, but so worth it!
