On the way back to the car I punctured, no spares, no patches, but I had a GU. So I stopped, ripped open the GU and spread over the gash multiple times until it had all but stopped leaking. I managed to ride the last 4ks with it, very light on the handlbars and only at 20km/h but GU did the job for a short fix. Straight to The Bike Shop new tube, rim tape and tyre. They looked after me! So If you get stuck when your out, use GU for a short term fix!
