Horse racing blog site, written by a group of young people (under 21), for young people, although I'm sure they won't begrudge older folk taking a look;-)
Their aim is to help bring a new generation into the sport of horse racing. The sites been going since late 2017. The articles are mainly previews for the big races, but also include interviews with horse racing personalities.
Aiming at the younger generation there's a big focus on Twitter and Instagram, plus a Rein It In podcast.
