A calendar of all races across all events can be found at https://midos.house/calendar.ics — by pasting this link into most calendar apps' “subscribe” feature instead of downloading it, you can get automatic updates as races are scheduled:

• In Google Calendar, select Add calendar → From URL
• In Apple Calendar, press ⌥⌘S or select File → New Calendar Subscription
• In Mozilla Thunderbird, select New Calendar → On the Network. Paste the link into the “Location” field and click “Find Calendars”, then “Properties”. Enable “Read Only” and click “OK”, then “Subscribe”.
