Hardrock Drops Spring

Announced on Instagram yesterday:

Hardrock is proud to welcome back GU Energy for 2024. Hardrock and GU share a rich and long history dating back to the 1990s when an early prototype of what would become the GU Roctane Energy Gel fueled their founder’s daughter to victory here. GU gel formulations were specifically designed for the tough conditions at Hardrock and we are excited to feature them at our aid stations again!

And further in the comments when asked directly:

That is correct. Spring Energy is no longer a partner of the Hardrock 100 Endurance Run.

Damn, things go fast.
