If you’re past it, then so am I! 37 here as well, but I feel fitter in some ways than I have been at any point in my life, but saying that, my recovery times are definitely a lot longer. I was probably as fit in my early 20’s but other than being almost twice that age, I’m a bloody sight heavier too, and that makes things more tricky… 🙂
What I notice most (in mountain biking terms) is that I have a fear gland now. I guess a career, mortgage, lovely wife and three cats probably make me hold back a bit and keep my wheels more attached to the ground than when I used to muck about as a youngster, but I wish I had the balls and skillz to enjoy the downhills with the kit I’ve got now compared to when I look back to my first few mountain bikes in the 1990s.
Ah, those were the days. I’m sure summers were longer then too. And the price of bread now, I say.
