Can you tell my weekend run was very windy? Took me over 8h to do only 55km & 1500m elevation 😭 But my it’s exposed up on the South Downs & i guess weather meant it was a great chance to check out some key bits of kit for upcoming #Winter200 ultra!! 😍 #runsky

Sundays were meant for faffing, so decided to find out what that new biofilm was coating our garden pond… 🦠 🧪

Running in the dark in a forest is brilliant. We saw loads of deer & frogs and heard bars & owls. But I woke up this morning full of scratches & bruises from tripping on roots & slamming into broken branches. But I loved every gruelling minute of it! 😍 #runsky

Lovely 50km run up through Epping Forest & back today. Got a bit incensed by the golf course watering the green during peak temp and evaporation! The law needs to be changed! #runsky

Not weird, but currently a record card of a line drawing I made of a diatom from Lesotho!
Record card being used as a bookmark. On the record card is a line drawing of a diatom called Hantzchia amphioxis

Like a ritual, before I start counting #diatoms from a new core, I always draw my own library of images of key taxa from that site. It makes research really slow going at first, but I find it quite cathartic. These are diatoms from a Lesotho wetland 🧪 🦠
Two images of hand-drawn diatoms, one above each other. Top drawing is of the genus Denticula, and the lower image is of the genus Nitzschia. Size dimensions are also written on the record cards

Not part of #lawnflowers challenge, but not the less interesting for it - Orobanche hederae, or ivy broomrape, growing amongst, well ivy, on an unmown verge in east London! #wildflowerhour

The London100km #ultramarathon on Saturday did not disappoint 🤩 Managed knee osteoarthritis pain successfully which was a huge relief as pounding those pavements for almost 14h was not kind 😅 *runsky

Going for an unplanned long long run on the hottest day of the year so far may not have been my best idea, but my, I loved every tired kilometre of it 🤩 #runsky

Camino Ultra organised a fantastic 50km #ultramarathon along the Lea Valley canal. The sun shone, and there was a party-like atmosphere at the end. I even managed to win the trophy for fastest non-binary runner 🥹 #runsky #lgbtq 📷 Dr Helen Farebrother-Naylor

My @spinerace.bsky.social didn’t quite go according to plan with my second ever DNF 😭 Taking the positives, I got to the start line, I have a new appreciation for how tough the race is, and for how tough the runners are who make it to the end!! #runsky 2nd 📸 credit: @andrewhendryphotographer

Went out for a cheeky 50km run through Epping Forest. The rain & the mud made it a bit treacherous by the end, but my, did I enjoy that! It’s all training for my @spinerace.bsky.social adventure! And raising money for a head & neck cancer charity! #runsky www.justgiving.com/page/anson-m...

“Last Dance at the Discotheque for Deviants” was marvellous, bringing to life my memories of working in Russia in the early 1990s, with political upheaval, economic tragedy & fledging gay scene trying to find its feet. Oh, and a murder (thankfully not a memory!) @pauldavidgould.bsky.social #lgbtq
