IRONMAN® 70.3®. It’s an IRONMAN-branded, no holds barred, incredible challenge. It’s tough.

And that’s why Lee Mackinnon is taking on IRONMAN 70.3 Weymouth, and travelling 595 miles to the start line (and then racing 70.3 more!)Macmillan

“I want to complete this challenge because it will be the culmination of a year’s hard work training and dedication.”

For those that don’t know, the “70.3” refers to the total distance in miles (113.0 km) covered in the race, consisting of a 1.2-mile (1.9 km) swim, a 56-mile (90 km) bike ride, and a 13.1-mile (21.1 km) run.

“As someone new to triathlons I thought a full IRONMAN would be out of the question! I have completed a few half marathons and cycled around the 50-mile mark a few times, which made me think that a 70.3 would be achievable with some tri-specific training.

I chose the 70.3 distance because I could complete each aspect individually but not combined. I would be exhausted after any of the sections, never mind jumping on the bike or pulling on the running shoes to get going with the next section; so the real challenge, and fun part, will be piecing it all together.”

So, what is Lee looking forward to most?

“I think waking up on the morning of my 29th birthday, pulling on my wet suit to complete the most difficult challenge of my life, and ultimately crossing the finish line will be such an amazing feeling.”

Lee has chosen to enter via a Macmillan Cancer Support charity place; pledging a sponsorship target to support people affected by cancer. As the charity partner for IRONMAN 70.3 Weymouth, Macmillan will be there to sing ‘Happy Birthday’ as Lee takes on the Weymouth coast.

“Ultimately, I chose to support Macmillan Cancer Support because sadly, my mother passed away last year after battling ovarian cancer very bravely for over 4 years. She was always supportive of my races and was there for me before, during, and after on race days. While undergoing her own treatments, she was supported by Macmillan nurses and it seems fitting to return the favour. In some ways, you don’t always appreciate the work the nurses do at the time because you are focused on your loved one, but looking back, I am very grateful the Macmillan organisation was there to support her too.”

Macmillan’s pledge to their participants is to be there until the last athlete crosses the finish line, cheering and supporting every one of the 2700 racing at Weymouth this September. Armed with music, foam hands, balloons, loud voices and cheering sticks, they’re known for being the loudest cheers on the course.

Lee’s advice to anyone thinking about taking on an IRONMAN 70.3 is that “if you are willing to train hard anything is achievable. Give yourself enough time to get used to all three sports at significant distances, especially any that are new to you.”
