Lockdown day #1. Sheffield is rewilding rapidly.

Lockdown day 2. Shades of yellow on the morning run. Old gold of skips, overflowing from spring-cleaned homes. A rider’s hi-vis vest. A custard-coloured car. Primroses, daffodils, forsythia. Celandines, a blaze of gorse. The patient progress of lichen on a drystone wall.

Lockdown day 3. Textures of water and stone.

Lockdown day 4. Thankful for views, fresh signs of spring each day, signs of hope in suburban windows. A moment of playfulness.

Lockdown day 5. Mapping the locality in running shoes: gravel, tarmac, trampled earth. Always more hills. Roads so quiet you can hear the cyclists.

Lockdown day 6. Amid all the grim news, a promise. Jostaberry and greengage buds, unfurling rhubarb leaves.

Lockdown day 7. Virtual fieldwork in Edinburgh. Hearing how Saughton Park is a lifeline for cyclists with disabilities, people recovering from mental illness, volunteers who plant the walled garden. Staying at home is vital just now, but pay attention to the effects. #parksmatter

Lockdown day 8. On the early run, a carpet of ramsons, an over-friendly dog, distant good mornings.

Lockdown day 9. Sheffield's Cholera Monument and Clay Wood. Reminders from another age: what matters in a public health crisis is not only how we cope during it, but also how we remember it, and what we change as a consequence.

Lockdown day 10. Lunchtime walk and a chance to discover one of Sheffield’s hidden gems: Lynwood Gardens nature reserve and community garden in Broomhall.

Lockdown day 11. A phone call comparing restrictions in Sheffield and Hamburg (in Hamburg, florists are still open!). Slow progress on an article. A brief look at the allotment: broad beans in flower, apple trees budding.
