As renekton, After going in with your Ultimate t, be prepared to fall back and peel for your allies in late game team fights.

To make getting on the enemy backline easier, group with your team but stay off to the side. If you flank from an unwarded bush, the enemy will find it harder to react to your all-in. Avoid splitting or being away from your team in the late game as the enemy will force a fight while you’re gone.

Play around your Ultimate t in the later parts of the game. Avoid fighting unless your Ultimate t is up. Fighting with out it will make the late game team fights much harder. Delay fights and be prepared to disengage if it’s still on cooldown.  As renekton, After entering with your Ultimate t, be ready to fold and peel for your allies in the fights of the late game team.
