Now, this guy is interesting because he is an Orthodox Jew who bikes and runs wearing his tallit katan (the garment with the black stripes) with the tzitzits swinging wildly beside and behind him. This young man participates in most of the local triathlons that are held on Sunday (Saturday is Shabbat), and he always wears the tallit katan. Thank goodness they are now made in cotton.
I have no idea who the guy is or where he prays. When I find out I will send him the photo.
