I've been mountain biking for about 3 years, and in that time I've taken two group clinics. One was solid and really helped me progress, the other was somewhat helpful, but definitely not worth the money I paid (in spite of supposedly being for intermediate level riders is was definitely geared more towards beginners). Anyway, I'm considering using a local coach for one-on-one instruction but my past experience and the cost/hour makes me hesitant. Anyone have experience with both types of instruction that can speak to the pros/cons of individual instruction? Any suggestions on questions I should ask potential one-on-one coaches beforehand? Any advice appreciated!
