My Marathon Plus never punctured, good job because I'm not sure I could get the bugger back off the rim to fix it. I thought I'd give tubeless tyres a try so I'm currently running a pair Specialized 2Bliss Trigger Pro 700 x 38's on my cross/gravel bike and they are awesome - pulled a half inch piece of hawthorn from one the other week, there was a hiss of air, a filament of white as Stans Sealant plugged the hole and I was on my way again. I'm sure I've had other punctures, just not even noticed them.
