Always check with your instructor if you are in doubt of an endorsement or your limitations. Don't be afraid to ask your instructor a question when ever in doubt about your training. FAR 61.93 (d) (2) (ii) allows your instructor to approve repeated solo flights less that 50 nm if your instructor has given you instruction in both directions along that route. And he can put restrictions on the indorsement. Probably including weather ,wind conditions and time of day. Check with your instructor if he's not available check with the chief flight instructor.
