Just started myself too. App (on iPhone) also crashed half way but assumed it was my fault. I now run with a watch and no music but am happy to provide moral support. We (OH joining in) have completed week 1 but not been out since Thursday so will probably do week 1 again from Boxing Day onwards.
i downloaded a couch to 5 k app and did day one run one today. it crashed i am looking for android app that tells of when i am half way round and is good! also looking for free mix of music for running. has anyone got some links? am not super unfit i Dont think as i do walk the dog daily. am a smoker though and plan that the running will help me give up. am a tad over weight. Dont do any other exercise though . i am mid 40's. love some support!
