I’m going to be doing my first gravel race (first and second actually as it’s a weekend) in September. I’ll be using my xc mountain bike though and wondering what tyres would be recommended. I was thinking Continental terra trail or schwalbe thunder burt.
Nice!!! Good luck 
They both look nice! A little flatter in the middle and more tread on the sides.
Probably consider smaller width tires to help with the rolling resistance since you’ll be on the XC bike.
Consider the following as well
- Panaracer GravelKing SK+
Work pretty well on the typical forestry commission tracks you’ll encounter.
I’ll take a look at the gravel king. I’d been going down the schwalbe overland 40mm but still open to recommendations
What is the event called?
I had no issues riding 37mm tyres in the dirty reiver, a friend even ran 35’s.
It’s the glorious gravel Keilder weekend.
Good know you had issues on narrow tyres. I’ll probably go for the gravel king sk.
