The Race HQ is at the Thames Young Mariners, Riverside Drive, Richmond TW10 7RX. Parking will be inside the TYM grounds and, if needed, along Riverside Drive just outside. The nearest train and tube stations to Race HQ are at Richmond (2.6 miles away, bus service from there) and Teddington (1.6 miles walk crossing Teddington Lock).

The Ham Estate is architecturally interesting 1960s housing on former gravel workings in a bend of the River Thames. Riverside Drive follows the river bend, and on the river side there is Thames Young Mariners and the Ham Lands, a site of Metropolitan Importance for Nature Conservation. Ham Fair is on Ham Common (not in the race area) the day before.


Course Details

These courses are also open to non SEOA members and newcomers.

Medals will be awarded to the first three qualifying SEOA members in each of the following categories: M/W 10-12, 14 -16, 18-40, 45-55, 60-65, 70+. To qualify, SEOA members must enter the applicable course for their age as below. If you wish to run up a class other than your actual age class you will be eligible in that age class but not your own age class – i.e. you can only receive a medal for the age class entered. If you wish to run down a class please select “Other” for the relevant course (e.g. a M55 running Course 3, would select “Course 3 Other” when they enter).

There are four courses with Age Classes allocated as follows:

There will be two races for everyone, with a short break in between. Race 1 will have individual starts every minute from 10:30 to 11:30. You can freely select your start time for this race when entering, among the times still available. Starts for the Race 2 are from 12:00 to 1:00 and your start time will automatically be 90 minutes after the time you select for Race 1, regardless of your performance in Race 1.

The finish for both races will be just outside Race HQ, with the start for Race 1 about 500m away and the start for Race 2 about 100m.

All controls and the Finish will be SIAC (touch free punching) enabled.
