Laura:

For as long as you can perform at that speed, keep doing it. Unfortunately, you will have to adapt and combine with other physical activities to keep 100% active, in spite of physical limitations.

I was diagnosed PD's 6 years ago and until 3 years back, I noticed a problem with my stride during running. It wasn't until my abductor muscle was affected in part due to the biomechanics of the stride that I realized I had to quit my running exercise and start swimming in order to avoid lesions. I did swimming for 2 years and combined with walking and stationary bicycle. I got bored of swimming and the stationary bicycle and kept walking. I have been walkling daily for 60 min in the past 3 years and it has been fun, relaxing and healthy (I walk in the middle of the woods). Recently, while walking, my right foot get stiff so I need to stop and stretch my leg. This happens during the 1st half an hour until my Sinemet first dose starts working. So if I want to continue walking I will have to adapt and slow down for a few seconds and start over. There is no other choice than to adapt. I am also considering swimming again.

This disease teach us to adapt. There is no other way to deal with it.

Wish you the best.
