Thetford (Norfolk) is fabulous. Well, the forest is anyway. A morning run on trail and track, in the sun, lifts the spirits, but tires the legs – 19km! Amazed to hear Cuckoo calling near the range (juvenile bird? I thought all adults were back in Africa, or maybe just leaving) and glad to see and hear Woodlark in the clear-fell areas north of Mayday Farm [Yes, these are now in BirdTrack].
