Lubrication to Prevent Nipple ChafingTo prevent this, use lubrication such as petroleum jelly, BodyGlide, SportSlick or Hydropel.
Cover up to Prevent Nipple ChafingIf lubrication is not enough, wear a sports bra or a nipple shield such as Neplex or Nip-Guard, or regular adhesive bandages.

ModestyA second problem for modest women is the show-through factor. Wearing a dark-colored sports bra is handy for hiding dark nipples and for being able to remove your shirt if it gets too warm, or to change shirts in mixed company.
Wearing a bra with padded cups prevents protruding nipples from showing, but most sports bras do not have padded cups. The Neplex nipple shield or adhesive bandages are possible solutions.
Whatever your comfort level is, don't let your nipples keep you from walking.
