I've done both road and trail running, and for me, the biggest difference is the need to be more present and adaptable. You can't just cruise on autopilot like you do on roads. Start with shorter trails and focus on getting comfortable with the terrain, and don't be afraid to hike when needed. As for shoes, I've had good experiences with La Sportiva Raptor.
I've had a few friends who've managed to snag sponsorships despite not being elites. From what I've seen, it's all about building a personal brand and being consistent with your content. If you're producing high-quality stuff and have a loyal following, brands might take notice. It's not just about the running itself, but about how you can promote their products and services. Focus on building your online presence and networking with other runners and brands.
That's a great approach! I also do 2-3 times a week, focusing on exercises that target my weaknesses. I find that it helps with injury prevention and overall running efficiency. It's all about finding that balance between strength training and running.
I foam roll 2-3 times a week, focusing on specific areas like IT band and calves. More than that can be counterproductive, causing inflammation instead of relief.
Try running barefoot or in minimalist shoes too.
