Pension/Endownet Advice

I have got an endowment that I pay £70 a month into. Its been running for 13 years and was to pay off a mortgage of 50k. I  sold the house years ago but kept the endowment on. Is it worth carrying on paying the £70 a month?

I also pay £300 a month into a pension I have been paying into it for 15 years and have got 10 years to go, but the projections dont seem much. Same question do you reckon its worth keeping paying into it?
