What is an Ironman 70.3, also known as a Half Ironman? It is one of the most grueling endurance races out there next to it’s counterpart, the full Ironman. 70.3 is the total distance in miles that an individual would cover in the race. It starts with a 1.2 mile swim (1.9 km), usually in a lake or ocean. Then it’s onto the bike portion which covers 56 miles (90 km) and finally the run of 13.1 miles (21.1 km), which is also the distance covered in a half marathon. If you’re wondering about the distances in a full Ironman then simply double the mileage in each segment.
Ironman 70.3 races are held all over the world with various terrains with the World Championship held in Las Vegas, Nevada. The full Ironman World Championships and probably more famous is held in on the big Island of Hawaii starting in Kona, Hawaii.
There are several challenges with this race, from just sheer time to nutrition during training and the actually race to having the proper equipment to be able to complete the Half Ironman. If you decide to start the journey of training for Ironman 70.3 be prepared to encounter several set backs and to challenge yourself both mentally and physically. I would recommend being able to complete at least 1000 yards (10-30 minutes) of swimming, 20-30 miles (1-2 hours) of biking and 7-8 miles (45-70 minutes) of running non-stop individually before considering attempting this type of endurance race. It would also be wise to consider competing in several sprint triathlons and/or Olympic triathlons before making the decision to attempt a Half Ironman.
