Boske moved to Newcastle at the age of 18 to work as a professional rugby player at the Newcastle Falcons. Earlier in the Netherlands he played at the Rugby Club Hilversum, where he played with Scottish international Tim Visser, among others. After three years he got injured during the County Cup Final and stopped playing rugby temporarily. Back in the Netherlands, he resumed his career at the Rugby Club Hilversum two years later, winning the Dutch title five times.

In the same period, Boske became active for BNN University, where he learned to make radio and conduct short interviews. After four years he switched to Veronica, where he presented several programs, such as the Brouwersch and De Fukkers programs. He participated in the Roadtrippers travel program in 2014 and 2015, with which he and two others competed against the StukTV team who could hitchhike the most kilometers in a given time.
