"The bar­ri­ers to entry for recre­ation­al run­ning and jog­ging are among the low­est of any sport. A good pair of sneak­ers and com­fort­able cloth­ing are all you real­ly need to get in the game. And mil­lions of Amer­i­cans hit the pave­ment every day. In fact, more than a quar­ter of all adult Amer­i­cans (26.4%) have gone run­ning or jog­ging in the past year, accord­ing to Nielsen Scar­bor­ough research."
