FREE SUNDAY HIKE - Viaduct, River, Castle & Lavender: A Darent Valley Loop
FREE SUNDAY HIKE - Viaduct, River, Castle & Lavender: A Darent Valley Loop
Looking for a Sunday that feels like a soft slice of summer? Join us for a beautiful 12โ€“15 km loop through the Darent Valley, where riverside paths, rolling green fields, and blooming lavender come together in one of Kent's most charming landscapes. This valley has been shaped by centuries of life and travel, and you feel it as soon as you step onto the trail. We'll pass beneath the towering arches of the Eynsford Viaduct, a Victorian engineering landmark that has carried trains across the valley since the 1860s. Further along, the route brushes past the historic grounds of Lullingstone Castle, a Tudor manor once visited by Henry VIII and home to the Hart Dyke family for over 500 years. From there, the path opens into the quiet lanes of Shoreham village and the purple shimmer of the lavender fields drifting across the hillsides. As we move through meadows, woodlands, and open countryside, the day settles into that easy summer rhythm where everything feels unhurried and lightly golden. It's the kind of walk where the scenery does the talking: the river winding beside us, the scent of lavender in the warm air, and the countryside unfolding in soft greens and purples โ€” a Sunday that feels sun-warmed, peaceful, and just a little bit dreamy. We will head to a pub near the station when we finish for a pint or/and lunch. ## ๐Ÿ“… **Event Details** **Meeting Point:** Eynsford Station (Start / Finish) **Meeting Time:** 10:15 AM for 10:30 AM sharp start. **Distance:** approx. 12 to 15 km **Elevation:** \~300 m approx **Difficulty:** Moderate **Pace:** Steady **Estimated Finish:** Around 2 PM ## ๐ŸŒฟ **Route Highlights** * **Eynsford Viaduct Viewpoint** โ€” one of Kentโ€™s most photogenic spots, especially in summer light. * **Ancient woodland paths** around Ashen Bank, offering shade and cool forest air. * **Shoreham Village** โ€” postcardโ€‘perfect with its stone bridge and riverside charm. * **Darent Valley Path** โ€” peaceful riverside walking with open fields and gentle breezes. * **Shoreham Lavender Fields** โ€” with sweeping purple rows and great photo opportunities. * **Lullingstone Country Park** and **Castle** โ€” meadows, woodlands, and a relaxed finish back toward Eynsford. This is a circular route full of **colour, greenery, and soft summer atmosphere** โ€” the kind of day that feels wrapped in the easy warmth of summer countryside. ## ๐ŸŽ’ **What to Bring** * Comfortable hiking boots or sturdy shoes * At least **2L of water** * Packed snacks * Sun protection (hat, sunglasses, sunscreen) * Light layers โ€” summer can still surprise * Good vibes and your best Sundayโ€‘summer energy ## ๐Ÿ“Œ **Important Notes** * **Stay Together:** Please stay with or behind the hike leader to keep the group moving smoothly and regular catch ups. * **Respect the Area:** Parts of the route pass through the **Kent Downs National Landscape** โ€” please respect wildlife, fields, and local guidelines. * **Group Rules:** Please read the โ€œAbout Usโ€ section before joining: [https://www.meetup.com/free-hiking-outdoor-fitness-and-social-activities](https://www.meetup.com/free-hiking-outdoor-fitness-and-social-activities?utm_source=copilot.com%20%22www.meetup.com%22) * **Safety:** This is a voluntary activity.

A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it. We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different. Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part! Who knew getting fit could be this fun? **TO BOOK**: It's essential that you book onto sessions via our website, using the link below; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals.

Thames Foreshore Visit - Limekiln Dock (Full Members only)
Thames Foreshore Visit - Limekiln Dock (Full Members only)
Running through the heart of London; the River Thames has played a central role in the history of the city, and when the tide is low, the capitalโ€™s longest archaeological site is revealed. Come along on Sunday 5th July to explore its history! **About the foreshore** I will be your guide as we will be going down to the Thames foreshore at low tide and walking along the foreshore, where we will have about 1h 30mins to have a look around for objects before the tide comes in. Where we are going is an old dock that leads onto the foreshore. I will tell you more about foreshore, the industry in the area and will be on hand to identify and date objects you find. Most objects you can spot sitting on the foreshore after being washed in on the tide (its eyes only, we are not allowed to dig or scrape the foreshore surface). You will find everything from bits of pottery, clay pipes, bottles, animal bones to ship items. Most of the things we find are from the Medieval to the Victorian period or you might be lucky and find something Roman or older. We should be finished by 12noon. **The Thames Foreshore is private land, so before we go down, I have to give everyone a short talk on health & safety on the foreshore. As per the conditions of my group permit, you will need to be present for this, if you are late, I won't be able to accommodate you.** **Footwear** The foreshore is very stony, but can be muddy in places, so please wear sensible shoes (preferably walking boots/shoes or wellington boots). Plastic gloves and bags will be provided. **Payment** This is for Full Members of the group only and will be free. **Become a Full Member** To become a Full Member (ยฃ14 a year), either: \- Pay cash at an event \- Pay via Bank Transfer \(TSB Bank plc\, Sort code: 77\-66\-65\, Account no: 00030809\, Account name: Cultureseekers) \- Pay via credit card on the day or in advance \([https://pay.sumup.com/b2c/QLAX8AUI](https://pay.sumup.com/b2c/QLAX8AUI)) \- Pay via PayPal\, send a payment to [general@cultureseekers.org](mailto:general@cultureseekers.org), using the โ€˜Friends & Familyโ€™ option Benefits of becoming a Full Member [here...](https://www.meetup.com/london_cultureseekers/photos/22974682/531979527/) **Afterwards** After we will head to 'Mario's Cafe', 139 Three Colt Street for a chat over a drink.

Regents Park Dodgeball, Rounders and Social/Board Games
Regents Park Dodgeball, Rounders and Social/Board Games
**Come join us for some fun in the park** This is a weekly social park gathering with optional sports and board / social games. 2pm Rounders / Dodgeball 3:30pm Social/Board games in the park- please sign up separately [HERE](https://www.meetup.com/games-friends/)[.](https://meetu.ps/e/PfHPb/z45zT/i) **How to play rounders** Not played rounders before? It's a traditional English sport for everyone, even the unsporty. Here's a video of us playing: [https://www.youtube.com/watch?v=E6Bya3T5W3k](https://www.youtube.com/watch?v=E6Bya3T5W3k) Rounders is a bat and ball game similar to baseball played by two teams. Your team will be either fielding or batting before swapping after the innings. When batting, the aim is to hit the ball, then try and run around the four posts. Your team gets a rounder if you make it round the four posts without stopping or getting out. You are out if when you hit the ball someone catches the ball before it reaches the ground or someone stumps a post before you get there. The rules will be explained at the beginning of each meetup with a practice round at the beginning. We play a slightly modified version of the official rules where if you are out, it's not game over for you. Your team will lose a life instead. This will give everyone multiple opportunities to bat. **It's very simple to pick up and the ball we use is very soft. We are very beginner friendly and the focus is on having fun rather than being competitive**. We attract attendees of all ages and sporting level. You are welcome to come and watch only too. We usually have a few people who do so while having a picnic and enjoying the park. **Come and meet us** Meet at 2pm in Regents Park. Here is the map of where we will be playing in the park (Cumberland Green): [https://www.notion.so/hyau/Rounders-at-Regents-Park-8bc419b72dde4aacaec3870d291636be](https://www.notion.so/hyau/Rounders-at-Regents-Park-8bc419b72dde4aacaec3870d291636be) You can also find us around here: [https://what3words.com/swim.jolly.youth](https://what3words.com/swim.jolly.youth) (just look out for our white rounders bases (long, white sticks) and you can usually spot us. Please feel free to bring food and drinks. The main rounders game will finish at 3:30pm and this is followed by social/board games or beginner friendly mixed gender football. **Social/Board Games** Please check out our [separate meetup event](https://www.meetup.com/games-friends/) for details and sign up there! **Football** For mixed gender football we aim to have roughly equal numbers of men and women and 3 ability levels (Beginner, Intermediate and Advanced).

Stop Guessing: How to Measure and Improve LLM Outputs
Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it โ€œseems good,โ€ and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, weโ€™ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. Weโ€™ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. Weโ€™ll cover: * Why โ€œit looks goodโ€ is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works โ€” and where humans still need to stay in the loop By the end, youโ€™ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
