I only cycle in the city, but I've switched from two flats per year to zero since I equipped Marathon plus. So for the last ten years or so, they've been a godsend for me.
100% would have got more flats with normal tyres this one over the last two years was an Achilles heel situation I think it was the straightest hardest thorn, and it bypassed all the tread.
Swapped from Schwalbe G-One to Marathon E-Plus on my E-Bike. Went from having a flat once or twice a month to no flats for two years now. Around 4000 km on these tires and still going strong!
