Great event but.... I really enjoyed this event back in my home town. It’s very well organised with clear direction and instructions. The pool swim is like most others, the ride although has a couple of hills is good and fast, the run is on grass so if your used to this you’ll be fine. However for me I like the bling and goodie bag, while you do get a couple of energy gels, there’s no chocolate/sweets or t shirt, also the medal is generic with the event details on the ribbon - this is just me being hyper fussy as I do like these little details and it’s not a cheap entry. Still it is a great event as said and I’d thoroughly recommend it if you want to add a new one to your achievements.
