Concept 2 has added a charitable giving aspect to the Holiday Challenge!

Here’s how it works: For every person who rows or skis at least 100k during the challenge, Concept2 will donate $.02 per kilometer (1000 meters) to your choice of the this year’s selected charities.
Create an online profile at Concept2, and begin logging your meters.
There are prizes and charity donations for those erging over 100k. Details can be found at: http://log.concept2.com/challenges/holiday
