Shades - Cathedral city do little packed cheeses. I've seen a colleague bring them over. They're roughly 10-20g per pack and lovely to snack on.
No idea about 100 so far. I was hoping it to be one of traviss's but i need to work out my calendar for next year. if everything goes to plan (touch wood) i'll be at 81 by the end of the year.
Iain - that's amazing pacing per mile. Its lovely to run with your son - did he enjoy it? Perhaps keep him to the shorter stuff until his fitness improves. I know my sister used to take one of her son's out for 4-5 miles on his bike but had to bribe him with an ice cream at the finish!
