Casting a spell and holding it uses visible components the hobgoblin could react to.
I’d think it’d take at least an arcana check to know that the spell you’re holding is Jump. So yeah, he could react, but would he necessarily be able to react in time to stop you from casting the spell? Not to mention, if he reacts just barely not in time and jumps haphazardly, one could argue the Wizard jumped farther and therefore wins.
