Shinsplints... my achilles heel

Went for my scheduled 7K run last night and was forced to stop after only 20 minutes... my lower legs were killing me! Later on I learn that I've got shin splints, not uncommon but bloody sore. I need to take it easy for a while, this means no running until my sports therapist gives the all clear. Normally I say "yeah! TV and beer all 'round" but now that I'm really quite serious about getting into marathon distance shape I'm a little gutted. Never mind, I can cycle to continue building my fitness levels. Other than that all's well!
