Left knee giving signals

Have taken it easy this week. Last night sprinted on top of Visamäki in 47.3 — a new PB. During warmup I felt something is not right in the left knee. Must be the result of the long asphalt run last weekend. Today I feel like the knee is not bending 100%. Let’s hope I can get it in shape before the run which starts less than 48 hrs from now.
