fiexd this in #78 /tracknow/backend/routes.py

page = request.args.get('page', 1, type=int)
    items_per_page = 5

    # Get the lap times ordered by date_created in descending order (most recent first)
    laptimes_query = Laptime.query.order_by(desc(Laptime.date_created))

    # Pagination: skip the items of previous pages and limit to items_per_page
    laptimes = laptimes_query.offset((page - 1) * items_per_page).limit(items_per_page).all()
