**Change in bag drop/meeting location** Meet outside Simply Theatre Academy, Gladbachstrasse 119, 8044 Zürich. (Thank you very much, Sloppy Seconds!) Although the map location has a different name, it is the same spot. https://maps.app.goo.gl/GzaLvSNkJ8mdqUfy6?g_st=ic Curiouser and curiouser - Just Alice and Saddam are haring (setting the route), so it looks like we're getting lost in Wonderland. Although it's an A to A trail, some points will feel like going down is up and up is down (but there will be a simpler route for our Tweedle Dums). We'll have a mixture of pavement and trails, and just the tip of a forest for all you Queens of Heart, as well as water on trail and some "Drink Me" bottles at a shot stop for the Mad Hashers. **Where**: Meeting and bag drop outside Simply Theatre Academy, Gladbachstrasse 119, 8044 Zürich. Although the map location has a different name, it is the same spot. Look for English speakers wearing running gear. **When:** We'll meet at 6:50 pm to start at 7:00 pm. There's a charge of CHF 5 for participating, which covers all you can drink beer/cider (and non-alcoholic alternatives) plus snacks afterwards. **All Welcome:** If you are new, curious, and want to get out of the house, stretch your legs, talk shit, enjoy a drink, and hopefully a laugh, then here's what you need to know: • We are a social running/walking group, physical fitness is not required, but a sense of humour is useful. • The aim is to find the '*Beer Stop*' at the end of the '*trail*' and have fun. • 'True Trail' is typically 4-7 km. Some will go less (especially those walking or walk/running), and some over-achieving fast runners will go further. • The '*Hare*', which changes each event (along with location), cleverly lays the trail (typically with flour marks) so that everyone reaches the end at the same time. • There is always a place to deposit your bag and sometimes a place to change. • **After Trail**, we group for \~20-40 minutes for drinks, snacks, and some fun. This '*Circle*' is typically outside, so leave something warm in your bag in winter (and bring a flashlight when it's dark). If you don't want to stand around drinking afterwards, you can head home. We occasionally all go to a restaurant afterwards. **Why bother leaving your warm & dry sofa?** If you enjoy getting outside, being around people, and doing something a bit different, you will probably enjoy hashing. Exercise is important, and this is probably the least boring way to get it. 'Hashing' and the idea of some physical activity to work up a thirst, have been around for almost 90 years and there are groups (*Hashes*) in most major cities. Its humor and 'traditions' can be explored on the internet - **or you can just come along and find out.** *See you there.* We are of many nationalities, all ages, full of misfits and idiots (at least there is no one taking themselves seriously!) and always welcome newbies 'Virgin Hashers' and visitors from other groups.

**Workshop Idea** We will explore and experiment with lighting that is often used on stages. **Model** Emma (IG @riel.life) is joining us as model. **What to bring** All you need is a camera with portrait lens. However, it might be beneficial to bring a wider angle lens for the stage overview! **Event fee** The event fee is CHF 100. **Attendance policy** If you would like to attend this workshop, please add yourself to the waiting list. The final attendance is determined by the host of the workshop! **Open to members and non-members.** Come for the photography, stay for the networking! Please understand that in case you cancel close to the event, we will ask you to pay anyway, as we have to pay for the model and the studio.
