Delani Diekmeier, 15, Wins Eppelheim Show-Jumping Class During Cancer Treatment Pause

Her return to competition came during a short break from Imaza therapy that has shown early effect.

Overview

  • She topped a Class L style-jumping event in Eppelheim, earning the class's only 8.0 score.
  • Riding Col d'Amour, she competed during a planned therapy pause documented by her family on Instagram.
  • Her father, former Bundesliga player Dennis Diekmeier, says time with her horse noticeably boosts her energy.
  • Doctors removed an adrenal-region tumor in 2025, but metastases were found in both lungs, and she later began Imaza treatment at University Hospital Würzburg.
  • The nuclear-medicine therapy showed initial response before Christmas and is expected to resume soon, with the competition outing also involving her younger sisters.
