About the goal
Break through the pain barrier to reach a swimmer’s high with this 21,125m goal taking you through the first 13 mile-markers of the London Marathon.
The half marathon goal is not for the faint-hearted as you’ll be pounding out 844 lengths of a 25m pool or 1,050 lengths of a 20m pool.
Remember, always warm up before exercising. Check out our stretching videos in the blog section.
In the pool
If you are a Mo Farah in the pool aim to cross the finishing line in one or two visits. If not, swim it in mile markers. Below are the first 13 miles of the London Marathon. Swim each mile in one or two visits if you can.
Don’t forget, every swim counts towards your goal, however small. Just log swims to reach it. When you have finished, set it again and complete a full marathon.
