Every Alzheimer Challenge up until now I rode my bike 300km from Groningen to Rotterdam in one day. This time I thought to mix things up a bit. I will ride my bike, run and walk with a total of 300 km's in May. The reason remains the same; to help find a cure for this terrible disease. Help me by either donating or sign-up with your own challenge. All donations go straight to scientific research that we so desperately need to keep getting closer to a solution. Thank you so much!
