The bike: The easy bit?
"...you're sat down so the bike is a rest..."
If only the bike section was a rest...
The bike leg is a key part of any triathlon, normally being the longest section of the race so you need to get it right.
Attacking the bike leg too hard can leave your legs sluggish for the run. Not hard enough and your already behind on the run.
My varied and dynamic mix of bike training will ensure you're in great shape for the longest section of the race and a pre-prepared strategy will leave you ready for the run.
