Toto Wolff must have imagined the summer holidays differently. The 
Mercedes team boss broke his elbow in a mountain-biking accident. The Austrian's left arm is now fully in plaster. His wife Susie reveals this via 
Instagram.
 A picture on Susie Wolff's account shows Toto walking around with an arm in a blue cast. 
"Action packed start to the summer holidays. Last picture shows how the downhill mountain biking ended for Toto," wrote Susie, herself being responsible for 
F1 Academy.
