Just come back from a great holiday in Greece where I swam for 30 minutes each day but didn't run. Came back home and did a couple of 5k runs and they went really well. During my third run I got a sharp pain in my inner thigh. Left running for 2 days but swam and walked instead. Ventured out this morning but after 12 minutes the pain was back again...hence the walk of shame through the high street back home! Anyone know how long one of these strains take to heal? Am thinking of leaving it alone now for 10-14 days. Unduly pessimistic?
