I'm training for the VLM (my first ever marathon) and following the sub 3:45 plan on the RW website. Training has been going well so far, but I'm going to South Africa 27th March - 15th April for work so I'm a bit concerned how I will be able to keep up with my training as A) Johannesburg is hardly the safest place to run B) It's at altitude so may struggle breathing wise to do some of my planned runs I am a member at Virgin Active so will have access to the VA gyms in Johannesburg. Anyone have any good advice how I can manage my training whilst in SA?
