in 2019 I spent my money on
3 pairs runners $245
3pairs socks $10
2 pairs of running shorts $50
splurged and got refurbished commercial treadmill $1k
divided by 365 days
each run only costs me about $3.6
Lower if i didnt get the treadmill
and you can get a good garmin watch for less than $100.
Running is dirt cheap compared to other sports
