Triathlons are perfect for anyone who can’t make their mind up what type of race to run!!
Joking aside, they are fun and very friendly events that can obviously be very challenging, especially at the longer distances. They do require a lot of equipment, training and organisation, and will require you to learn a load of skills that you just don’t get in other races.
The probably the best thing however is the combination of speed and intensity with endurance, which other sports just can’t match. So if you like doing 5K’s but want a bit more of a challenge, Triathlons could be the way to go.
