Chastity and orgasm denial discussion

I’m seeking advice on exercising while in chastity. Specifically running. Info/ideas on how to keep a QK from causing pain or too much of an annoyance while out. It’s getting to be the late spring here, and so with warm weather coming, I want to note that I do all my running outside. The background is real simple. My wife/KH and I always take spring off of chastity (various reasons involving work and travel), and this time during the break the two of us started training for a half marathon. Now, with summer getting closer, I am getting the itch for another lockup and so is she. But, we are concerned that doing so will impact my continued training.
