Cycling tends to have more expensive gear, but have you ever heard runners geek out about shoes, socks, chafing remedies, mobile hydration solutions, “gels,” etc.? Definitely not opposite ends of the spectrum.

But pretty much all that is optional and the rate of performance return for investment is minuscule in running compared to biking.
If you shop around you can get good enough running shoes for $50. After that you need shorts, underwear that won't chafe a couple shirts (and possibly a sports bra). For under $100 you can have everything you need to train for and complete a marathon.
