This post is an attempt to build a larger participation in this years Winter Challenge on Funbeat.

This will be the fourth winter in a row that I challenge my work out friends on Funbeat to a swim run event. Each year the number of people participating as increased and the times are getting better and better.

The rules are simple:

• Swim 1500m – without the ad of equipment
• Run 5km – times from a treadmill not allowed

Someone even came up with the events hashtag #ryknosaqua.
