In college I had no money to ride, but desperately wanted to so I called around to every barn within 40 minutes of me and finally got a chance to be a working student a few hours/week for a trainer at a lesson barn. The deal was one 30 minute lesson for every 15 hours I worked, for a whopping hourly “pay” of just over $3/hr. Of course, the trainer was only there a few hours after school on a few days per week - I often spent more time in the car commuting than I did actually working (and each trip probably cost me $10 in gas). In addition, the BM did everything she could to try and short me on hours. I usually ended up getting a lesson every 2.5 weeks or so.
I considered taking a gap year after college to do a full time working student position - the only opportunities I could get was an unpaid position (board was included for one horse, not that I had any money to buy one!). There was another position I got an offer for - a trailer on site and $200/mo stipend. I only give the second one some grace because it was a nonprofit OTTB rescue, and actually considered it briefly, but decided not to since my parents were kicking me off their health insurance and getting injured seemed more like a “when” than an “if”. Both of these were sometime around 2016.
