Suggest Remedy For Running Nose While Walking

Hey just an odd thing that's been happening for 2 years or so but recently started to annoy me enough that I am seeking help. Basically I walk to work (65 min) and home again every day and always when I have been walking for a few minutes, my nose just starts running. I usually refrain from blowing it until I reach my destination, because otherwise I end up blowing my nose like 2 - 3 times a walk. When I am at home or the office then its generally fine and I don't need to blow my nose anymore than normal, but it's just when I walk it starts to get frequent.
