Shows top 10 runs on popular running distances

It would be really nice to track progress over the years on several distances. 

E.g a Top 10 of:

- Fastest 5K runs 

- Fastest 10K runs 

- Fast 21K runs (Half marathons) 

- Marathon 

- Top 10 longest runs 

Today you have to remember your PRs on the different distances. 

it would be a really nice feature!
