RP Cheltenham Festival Guide

Weatherbys one is far better, more depth

I get them for my preview night. Its an interesting enough read and has loads of stats.

I agree with the above. The RP guide is better for outright stats, Weatherbys for analysis. A few of the features in the RP one are excellent, but overall they are variable. I find the RP guide handy as a rapid reference. It also gives stats in RPRs (rather than just ORs) which is handy if you want to use the RP's website/racecards. Overall, I'd say it's just about worth the price.

does marten julien still do a book for cheltenham and if so is it  worth buying

He does yer, well worth a read but a bit pricey compared to others. I always buy Paul Jones' book
